Much better than making people dependent on those who control the mechanisms for allegedly limiting unexpected expenses; that's just a plan for increasing social control available to elites. High density housing with shared kitchens and bathrooms sounds like a dystopian hellhole designed to strip people of their dignity, and that's something you think is a good thing? We already saw tenement buildings in the 19th century.
You can argue about taking down the rich (they have too much power, your jealous, etc), but don’t for a second pretend you’re doing it to uplift the poor.
And what mechanism do you propose? Just a 100% tax on any gain over X%? Do you realize how easy it would be to then just sell at that threshold and invest in something else?
We didn't even have the minimum wage 100 years ago in the United States. How are you going to deride people for not offering solutions, then, when they offer viable solutions, attempt to magically will-away history?
These ideas aren’t new. The idea of taxing the wealth even more is ALSO not new, and we already have tried it and had it fail. (France has tried this, as well as other European countries, with usually disastrous results).
Even if you could magically trap all of them in the US and wealth tax them away, it’s a meaningless drop in the bucket. Seize all of the money from everyone with 50 million+ in the US and you don’t even have enough to pay for Medicare for all.
