It's a key reason why technological improvements tend to increase rather than decrease inequality. Technology, generally, appears to serve wealth and power.
I'm not fully convinced this is a universal rule, though it seems at the very least a strong bias. It seems to fall from the observation that "all machines are amplifiers", which means that all machines are force multipliers.
It may be that there are technologies which are dissipators and can be used to deflect or divert attacks, though these still seem to favour the more heavily-capitalised party. Shields rather than swords or range weapons, or perhaps distracting / obscuring capabilities.
What makes for decentralised systems is increased frictions, whether physical, political, cultural, or social.
Where transport is expensive, materials are locally sourced, talent participates locally, government and business operate locally.
It was the factory system, mass production, transport, and advertising which allowed one factory or manufacturer to serve the whole world. Mind: specialisation means that there are probably many individual niches which can be filled, though horizontal and veritical integration may carve into this as well.
My point is that it's trivially easy to understand the negatives of things like car dealers and real estate agents (pretty much everyone I know hates dealing with them), but I think we're just starting to come to terms with the potential negatives of having huge, geographically broad, open markets where there are very few winners.
The same people who consume also need to be either small business owners, freelancers, or employees. In fact without the money from that, they couldn't be consumers in the first place.
So what's bad for a consumer role can balance out or be very good if it helps keep more people making money as opposed to the "efficient single corporation with the minimal workforce" selling everything". Such corporations are how many small towns in America turned into wastelands...
You need middlemen, even if it's not the most efficient productivity wise, because it helps make more money go around, stay local, and keep communities livable.
The alternative is a future with a 20% working, a 0.01% corporate overlords with the top end having Bezos style riches, and 80% barely making ends meet, living in slums, and we're getting there...
What I proposed is the opposite: laws working against those mega-corporations in favor of many smaller corporations.
Only the people, through law, have the power to do that. The big corporate overlords, left to their own devices, wont be able to fix the problems they created. They will only make them worse.
Chile during the Pinochet Regime is an excellent example of the Neoliberal system not delivering on the promises, as hn_throwaway_99 mentioned, economies of scale simply take over any benefit of low gov friction "free markets", and any small advantage over time becomes an overwhelming one. At which point it simply becomes a mathematical snowball effect, reducing or removing government barriers of entry won't make your particular gadget or doodad be able to compete in quality nor cost against one produced by a huge mega-conglomerate, if anything that mega-conglomerate will see if it can steal your idea or buy the patent (gov!) so it can improve its own. It is the same thing that happens in South Korea with the Chaebols
Anyhow, point being, the Kansas Experiment failed[1], Chilean Chicago Boys Experiment failed to deliver after ~17 years of authoritarian rule(When Pinochet left power country had a ~40% poverty rate)[2]
This leads to the simple idea that the less friction your system has to accrue wealth the higher wealth inequality will be, and then the goal should be to make it as easy as possible for everybody to make their own start ups, but to create as much friction as possible for said startups to gain too much economy of scale momentum. Where the threshold of where that line would be, be left to policy makers, and ideally something politically independent, akin to the central bank

It's actually below most western European countries in most global metrics, including such basics as infant mortality. It trumps most in gun deaths and incarceration rates though, so there's that...

And those countries have much less megacorps and "economies of scale"....

This is meaningless because it is not normalized, the EU has a higher purchasing power parity than the US which is what your average citizen truly cares about

Post-Hard Brexit it will probably change, EU PPP has already been damaged by the current Brexit scandals, and the last few years of increased US Dollar interest rate has increased relative US PPP, but because of income inequality those financial changes aren't really transferred to the everyday US citizen
Also, the difference in raw incomes is mostly based of the so called "Exorbitant Privilege" the US has for having its currency be the default world reserve currency, it is quite easy to understand when one comprehends that the US central bank basically "prints gold", and that like ~60% of all international transactions are done abroad but with the US dollar as transaction medium
I find it rather unbelievable that things are cheaper in Europe. A few years back, I used to work for a multinational, which opened an office there, and some people I knew went and at least one or two stayed, which lead me to idly consider the idea of being an expat, and my cursory research indicated salaries are lower and the cost of living is higher.
And before that WW2 levelled entire cities, like capital of Poland was obliterated as it was bombed once when Germans took it, once when the Polish rose up, then again as Soviets took it.
At the dawn of computer era there was a wall, landmines and machine gun nests going though the centre of Berlin.
Isolate your comparison to northern Europe, spared by war and Soviets, and the difference in GDP is no longer in US favour.
2) Just look at the chart I linked to - on decadal timescales, the EU was catching up to the US rapidly and then plateaued, in more than one cycle. No idea why, but something significant was happening and then stalling. Obviously history wasn't retroactively occurring and being eradicated.
1) You can't brush off foreign occupation 29 years ago as cherry picking. This dataset starts in 1960s, when all of Eastern Europe were soviet puppets. There is nothing comparable in recent US history.
Of course there is. What transition happened in the US in the 60s, that the country is still not completely out of? You'd know instantly if an American was using it as an excuse (as is quite common) for not matching various European metrics.
For one, the EU has dozens of ex Eastern Bloc communist countries (including areas of ex-USSR) which still play catch up and wages are still much lower.
Second, money is not everything. If the state, every day life, cost of living, etc is set up in a good way, you can get 2x or more the quality of life for half the money.
If such changes were brought about, the increased taxes could go towards things like infrastructure and social welfare, which would actually help people, unlike what billionaires pretend is fair compensation to their harms upon society, when in reality they give back very little. Bezos and Musk for example, both got into the space industry instead of putting a lot of their wealth back into philanthropy. The seeming odd one out is those who are like Bill Gates, who do actually give back a massive portion of their wealth.
On the contrary, if you look at businesses where there is not huge consolidation, it is often because there is "market unfriendly" regulation. E.g. there are many rich car dealers spread throughout the US because they've put in place so many anti-competitive regulations. While I'd love it if Tesla could sell direct everywhere, it also means a lot of this wealth that currently stays relatively local would get sucked up by a Silicon Valley corporation. Same thing goes for Realtors and the real estate business.
As a consumer I love more open markets, but I don't think we've fully addressed the consequences of how this leads to greater inequality and consolidation of services.
