The US economy is a complete dumpster fire for those of us worth less than seven figures. Big tech monopolization does not strengthen our productive capacity, and breaking up the big tech companies won't weaken it. If anything, it will strengthen the economy by making it more viable to found a tech startup without the explicit goal of being bought out. We aren't "killing" our software industry; we're revitalizing it.
Not sure what you mean, you can invest in VTI, wait 30 years, and hit 7 figures real. The US economy is stronger than almost every other economy on the planet and is so even for the non-rich.
Look at the risks a poorer person in the US has to contend with, many of them life-ending expensive, as well as the difficulty of finding places to live that offer decent job markets, services, amenities, and are affordable.
Life here can get really ugly for people that are well above the 'poverty line'. That's not to say it's really the overall economy making things hard for them, but more like microeconomic constraints. However, that's the lens they see the economy through.
I think a better parallel is the late-20s early-30s Robber Baron breakups. There's been much ink and elections spilled over how that anti-trust era contributed directly to the proliferation of post-war innovation (e.g. https://bookshop.org/p/books/goliath-the-100-year-war-betwee...)

But sure. Kill your software industry. Does the US even know to do anything else? Does the US even manufacture anything physical anymore? Last I checked tiny little Denmark produces more wind turbines than the US and tiny little Switzerland produces more CNC machines than the US.
