Taxes don’t mean shit to the wealthy. They will find a loophole to exploit and end up never paying taxes.
Even still if they had to pay more taxes it’s nothing to them. They are swimming in money. It’s not even about the money at this point. They want to undercut the poor so the poor stay poor.
Taxes don’t have to be to punish the wealthy from purchasing homes, it just has to be enough to make it so they can’t profit from it.
If they can’t profit from buying homes, they won’t do it.
If they can buy 10 houses and pay $2000 / year in property taxes per house to hold on to it, but the houses go up in value by $20k per year, they profit.
If instead they pay $2k for the first, $4k for the second, $8k for the third, etc. there is no incentive for them to buy more than 3-4 homes since they will pay more in taxes than they are gaining in value.
