"Can you give some examples of that? Most of the poor have no wealth in the first place"

They don't have wealth arguably because it's taken by those with considerably greater leverage.

Asymmetric parameters like avoiding regulations regarding 'full time employment' (i.e. Uber) is one very common way that employers keep workers down.

It's not always obvious either - just as H1Bs can create a lot of value, in many cases, they are point blank just used to suppress wages.

Consider many wealthy folks pay a lesser net tax rate than others due to income from capital gains - of course there is some rhyme and reason behind the fact capital is taxed at a lower rate than income, but one might argue that on the whole, this isn't really fair at all and is one of the primary drivers of inequality.

I don't think inequality is inherently a bad thing, but too much of it is bad, and we should always be looking for ways to get people 'empowered' into positions wherein they can create real value and grab a fair/share piece of the pie. And we have to remember there are always people who won't be able to do that, and that we have a responsibility towards them as well.
