I replaced my old, fairly high end pc with a fairly high end Beelink a few months ago, and it's working out fine. The beelink mini is cheaper, better and faster in every way, and will end up as about 5% of the trash my old PC exists as. I'm not sure I'm going back to full-sized desktop pcs, despite being a game artist/game developer who needs somewhat high specs to do my work.
Block, baby, block. I've been blocking tons of communities/magazines I don't want, and that really helps shape my feed into something I'm not annoyed at.
A grandfather clause could be added, so that 'from now on' people can't buy more than 1 home. But there are plenty of less severe ways to fix the problem. A lack of solutions isn't the issue, anyway. The problem is that rich people who control countries don't want to fix housing problems, since they are often the people benefiting.
People aren't corporations. In the US, corporations are considered 'people' for legal purposes. Anyway, making it illegal for corporations to buy investment houses would be great.
Honestly, I'm fine with the normies staying on Reddit and Twitter, while all of us 'new cool' folks explore our rebel alliance.
