Neither do I. And I think that we should address gentrification, real estate investors, mortgage lenders, and usurous landlords. I think we should also encourage employers to move their operations to suburban and borderline rural areas to allow for more affordable living options for their employees.
Gentrification is a function of society, not something that can be fixed.
A neighborhood being shitty drives down prices. Make the neighborhood no longer shitty and of course prices go up! The idea that you can fix up a poor neighborhood and leave the prices alone is bonkers.
As for moving to the suburbs--if it's viable businesses do this anyway for their own bottom line.
I actually think it's critical to a thriving economy to have some degree of income inequality. We've got to have some people with enough money that they're willing to take chances with it - that's how we get investments in start-ups, innovation, etc. If income is too evenly spread, the marginal value of a dollar remains relatively high, so that people will generally prefer to spend that dollar on themselves and their current quality of life. In short, you've got to have some Musks in the world in order to get Space-X. Ideally, we'd have a smallish group of exceptionally wealthy people, with highly diverse interests that they're willing to invest in.
You also need something to drive people to put in the effort to get the skills. If a high skill job pays little more than a low skill job why would anyone spend years learning how to do it?? A college degree (earned at no cost) still requires 11% more income to just break even. At the high end it can be 33% more just to break even. And note that this is neglecting the marginal value of a dollar--in practice people put less value in every additional dollar, this is difficult to quantify but given the even choice expect most everyone to choose the even income.
There are challenges, of course. One is that there's a risk of getting a small group of highly wealthy people who all have the same interests - then you get over-investment in a narrower range of fields with only marginal differences in outcomes between those investments, and entire sectors of possible innovation get ignored due to lack of interest. Another risk is that you end up with some of those highly wealthy people being uninterested in investment at all, and then they're essentially Scrooge McDuck (the Waltons are a prime example of this). I don't know where the balance point is.
Except Scrooge McDuck doesn't really matter. So what if he has a vault full of gold? Once again, at the level of society money means nothing. His vault of gold sits there adding nothing--but neither is it taking anything away.
