imagine the shitshow if you had to pay extra every year if you owned a house outright but the property values kept going up?
You mean property tax? Because almost every state already ups your taxes if your value goes up. In TX they reassess every year. In CA they had to pass a law to STOP doing it (now it only goes up by a flat rate every year if I remember correctly), but that has led to new loopholes to avoid tax.
But I do see your point. For normal people, their main or only asset is their house. They need to live there and aren’t necessarily getting 10% pay raises when their value goes up 20%. If my house were taxed at its current value, I don’t think I could afford to live there since I don’t own it outright.
The big issue is that banks give out very low interest loans based on assets that have unrealized gains. Those loans are used as income by wealthy people but aren’t taxed by the government. They are “taxed” by the banks getting some money in interest, but the government sees none of that and it’s at a much lower rate than capital gains.
