Spain and Brazil push global action to tax the super-rich and curb inequality

I think increased automation and now AI are making wealth inequality problems inherently worse.

The existence (and prevalence) of food delivery work alone is a depressing portent in my view: If delivering food for objectively shitty pay is still a viable option for a lot of people, that signals to me that human labor has become borderline worthless (even in a wealthy/developed environment).

That makes the "american dream" (=> start from nothing, do a good job, become wealthy) increasingly less realistic.

I'm also afraid that this (preventing wealth inequality from getting out-of-control) might be a "practically unsolvable" problem for democracies in general (just like managing housing and public pensions): It is too easy to "sabotage" democratic progress for the negatively affected minority (and that minority is exceedingly powerful/well-positioned, too).

In the US, over the last 45 years, work has increased in value about 3.5% a year, and the S&P about 9.5% a year.

Work is not valued, wealth is.

This is exactly what I mean-- I think also the whole housing affordability is just another side of this coin: Buying a home grew more expensive (in terms of median income) for decades, and that alone is a huge problem in my view, with no realistic solution that I can see (=> except demand implosion from a shrinking population, which would probably create twice the amount of problems that it solves...)

Housing costs in the western world is the root cause of everything. Housing costs on a monthly basis increase to take all income, because the demand for housing is higher than the supply.

You can't simply reduce your consumption, because you are reliant on everyone doing the same thing.

Rent controls don't help because that means housing simply has to be rationed in another way which is typically worse.

The solution is to increase housing supply in high demand areas.

Has anywhere tried rent taxes to fund new construction?

It'd need to be strictly tied with a viable building method, to limit NIMBY problems, but would accomplish the goal.

If rent for class Y housing is $A, and the target price is a lesser $B, then tax the $A-$B difference at a high rate, with 100% of the tax proceeds being used to directly fund new class Y housing creation.

Bigger delta = more funding for new construcion

If there's demand, companies will fund new construction. The problem is that planning, zoning, nimby restrictions means you can't

The invisible hand of the market certainly isn't all powerful, just like chickens aren't spherical and travel in a vaccuum, but when you stick it in a plaster cast as we do with housing, it becomes useless.

If you tax rental, what about owners? They won't care, they don't pay the tax.
