They are resisted because they threaten the status quo of the oligarchs and the useful idiots they are able to convince. In my country, they mostly do it by doing barbecues, concerts during the campaign, giving people in the countryside buckets, umbrellas a bag of rice and bottle of oil, and lots of TV and TikTok propaganda. In the US, religion seems to plays a much bigger role.

We've known for years that starting school at 08.00 is detrimental to school-aged children and teenagers, but we keep doing it.

But work is ~~9-5~~ 9-6, can't have flexible hours. Everyone knows a busy employee is less likely to get weird ideas like unionizing.

We've known for years that WFH can be just as productive and even more so than RTO, but we keep doing it.

But you can't control and micromanage the ~~slave~~ employee if they aren't physically present at work. And also, we need to keep the employee busy on the 1-2hr commute, see above point.

We've known for ages that housing homeless people helps them and society much better than criminalizing them, but we keep doing it.

You mean the poor landlords lose the bread from their mouth and not get paid rent?

We've known for ages that repressive stances on drugs are counterproductive, but we keep doing it.

Stealing the bread of our poor military complex and police forces? Can't have that.

We've known for ages that a 4-day workweek results in gains for everyone, including the owner class themselves, yet we keep on doing 5.

See point #1

My point is that it's literally a class war between the oligarchs in power and the rest of us.
