There’s nothing stopping Vegas (or other cities) from doing something even smarter. Nothing except people and enough competent companies who can implement. At least Boring Company is helping with the latter and providing more options.
Also, Kim Jong-un and his people make decisions collectively: Kim suggests something and when his people agree (or just don't die), decisions materialize! These decisions are collective because nothing would happen if Kim acts alone.
Wait. Maybe "collective" does not mean "multiple people working together" but cooperating towards common and mutual benefits. Those who cannot afford not to work for those who owns the capital don't make a "collective" with those who own them and decide how things must be (e.g how much Amazon can pay less tax than individuals and small businesses). Also, democracy is more than a word: when you have no choice but to vote for candidates who support billionaires, there's no "collective" behind the election either.
And those 'lords' whatever that means got that rich because they invested their personal time and resources into things that ended up working out and that's why they have the resources they have.
EDIT: To be clear: markets≠capitalism
Markets without ownership are mostly meaningless. All models of market socialism are mostly theoretical. Even the inventor market socialism didn't get far in implementing it.
Yes there are some markets that can exist outside of that but not a central organizing principle of an economy.
> "they got rich cause they worked hard" is a very shallow take
The worked hard on the right idea. Its not a 'take' its a fact'.
I didn't say 'anybody that works hard will be rich'. That would be a shallow take.
