If the result of that is excluding lower-income people from living there, I disagree.

1. Homeowners being a powerful political bloc and using that power to stop development is part of the problem in the first place

2. Buying a house makes sense if you're a starting a family and/or setting down roots, but that's not everyone's situation. Students or young professionals get utterly shafted by lack of rental housing, because they don't have the income or the credit to buy a house, and they don't intend on staying long they'll get eaten by the transaction fees.

You're not entirely wrong. Housing should be seen as more than just a place to live but less than a moneymaking investment - it should be seen as basic housing security for those who want roots as you said. NIMBYs do screw things over sometimes, I agree. And liquidity in mid-term housing supply is important. But I suggest that it would be better for society in the long term if more people had a stake in where they live.

By the time you’re a young professional your credit is honestly pretty decently established, hell I tried to buy a house on an internship and they qualified me for a 250k mortgage with a 48k salary.

Hell I know guys that went straight into the workforce after high school, nothing stopped them from financing 6 figure pickup trucks, and those depreciate badly in comparison and are harder to repo and re-sell.

Problem is, most places with work that won’t get you a place to live. Houses used to be 3x the median income, nowadays it’s more than 10x.

The idea of housing only being for very established people is new, and only due to its staggering costs nowadays. When my father moved to a town to wash dishes at a pub, he bought himself a house. Cost him 3x his salary.

The point is that the problem of mega corps is greatly overstated, and isn't really the root of the problem anyway. They are just an easy scapegoat.

Take them away and private "mom & pop" land lords quickly fill the void, and usually are much more stringent about who they will rent to and what they think a fair rent is.

Right. It's still the same amount of houses, and the same amount of people wanting a house, so the price is not going to shift much.

While I agree the mom and pop landlords also pose a problem, they don’t have the capital to outbid new buyers by tens of thousands, or to leverage dozens of existing properties. Bidding against them is not a perpetual David vs. Goliath battle.
