> Closely related to poverty is lack of social mobility.
It's not just closely related, when considering income inequality the two converge. It's simple arithmetic really. When poverty wages are a lesser multiplier (i.e. income inequality were less) of wealth wages (let's say 2), then it's obvious how to lift oneself out of poverty, split a home with another person earning an income.
> you don't have to grow up rich or even upper middle class to get rich as a startup founder, but few successful founders grew up desperately poor
Sure, but a rich founder has a clear advantage, in the same way that a founder at Harvard has a clear advantage. It's a lot easier to ask a friend/colleague/parent for money than a stranger.
> For example, let's attack poverty, and if necessary damage wealth in the process.
Yes. The way we attack poverty is to spend money to improve schools, spend money to improve transit, spend money to provide food for low cost. Where does that money come from, taxes. If we just talk about fixing poverty, we run the risk of not actually spending money and fixing the problem. Ignoring the greater context of politics, and the almost 100% sign on of republicans to the Grover no new taxes pledge, in order to actually get a mandate to fix anything, the alternative has to be upfront and direct about taxes.
If you'd like me to address arguments directly feel free to respond with something less dickish than telling me to read an article that I've already read.
