I agree with the platitude, but subsidizing interest isn't giving money to poor people-- it's cutting a check to a bank, using tax money that rich people avoid paying. If you want to increase the supply of cheap houses, you have to build cheap houses. If you want to lower the price of housing, artificially injecting a bunch of money into a market is going to raise demand and do nothing for the supply. Nevermind that in the US in particular, the problems exacerbated by a massive demographic shift towards dense urban centers that were not bombed out and rebuilt in the mid 20th century and therefore do not have housing stock appropriate for the lifestyles of today.

You also ignored the comment that subsidized interest is already an existing thing in the US and that the last time they tried giving houses to poor people that they could not afford to maintain, it crashed the global economy and was the single greatest wealth transfer towards hedge funds in history. NYC's newest policy (after moving away from the structural failure of consolidated public housing) is that all new construction must have a certain number of low income, middle income, and high income units. That's an actual supply side solution and the ratios and income thresholds are determined by the already existing demographics of the neighborhood as a way to fight both gentrification and white flight.

I'd be happy to have an actual policy discussion rooted in facts, but you can't wave your hand over a stack of tax revenue and solve structural problems about housing stock, centuries of segregation, and the horrors of capitalism simply by wishing it away. There's a lot of actual work to be done, and some of that might mean replacing historical housing districts with high density, mixed income developments. But that won't ever happen, because the generations before us relied on home ownership as an investment vehicle for retirement and have spent decades campaigning against stuff like public transit, low income housing, and the existence of homeless people anywhere near them.

Feel free to diagree, but I'd rather give my money to a homeless person directly than subsidize the actuarial risk of a billion dollar investment bank via the coervice use of state violence if I decided not to pay my taxes.

Like, if you can't come up with 3% of the value of a house (the down payment standard for subsidized homeowners in the US) how are you supposed to repair a roof or replace a major appliance? More government grants? From what revenue?

if the proposal is to disposses all the property owned by billionaires and use that to fund a reimagining of our cities such that they're built for people and not cars, I'm game. If your idea is to raise taxes on working people to subsidize other working people while the banks, the construction firms, and every material vendor takes a profit, then fuck that.

Most of Sweden's housing is owned by local governments (kommun in Swedish), but it's also a 5 year wait list to get anything, impossible for immigrants/students to find anything because they don't qualify for the queue immediately, and tied to a specific place. So, if you get a better job somewhere else, you're still fucked because you would have needed to get on their queue 5 years ago or pay the inflated "market" rent because the supply of non-state-owned housing is so low. Denmark and the Netherlands have the same problem, but perhaps that's more understandable considering their absolute size and population density.

As a side point, are you aware that the government has relied on deficit spending for more than a decade and that every new dollar spent is a dollar + interest that must be paid back to an investment fund?

For example, every time you ride the subway in NYC, you're paying something like $.30 to Chase bank to service debt the MTA used to renovate the system in the 70s.
