I would wager that the overwhelming majority of people moving from rural to urban areas are doing it to better their bank accounts.
You do raise a valid point, which is that a car is a luxury. Having lots of land is a luxury. Having kids is a luxury. Living in a long Urban center where the grocery store is a 2 minute walk away is a luxury.
It's up to the people receiving the UBI to decide which luxuries they want to spend it on. You can't have it all unless you can earn enough to pay for it all.
I never said conditions like that should be added, only that we shouldn't give out enough UBI for people to live a luxurious lifestyle, which is what rural life really is in America, in a way. Think about it: what would happen to poor, rural Americans if we jacked the price of gasoline up to European levels, where it really should be?
>Living in a long Urban center where the grocery store is a 2 minute walk away is a luxury.
It's really not, it's simple geometry. If you pack people into a dense urban environment with tiny little apartments and remove the luxury of a car and lots of land, then a 2-minute walk to a grocery store becomes almost automatic. It's a tradeoff: you simply cannot have a 2-minute walk to a grocery store if everyone has a separate, freestanding McMansion with a giant yard. Anyone with a basic understanding of geometry should understand this. Put everyone into tiny apartments in high-rises and a quick walk to the grocery store is easy to accomplish (make sure the urban area has mixed-use zoning though).
You're actually proving their point for them:
>> which is that a car is a luxury. Having lots of land is a luxury. Having kids is a luxury. Living in a long Urban center where the grocery store is a 2 minute walk away is a luxury.
If your optimizing for least effort for a given income level moving to the city is a no-brainer since it's where all the easy money is.
You can say that about literally anywhere. It's a matter of how doable it is, and how much effort it'll be, versus the reward, compared to just going somewhere else. The simple fact is that there's far fewer jobs in rural areas, and also there's far, far fewer good-paying jobs.
Cities arent perfect. I'm absolutely stressed over the hectic pace of a large city. But I'm not depressed and hopeless like those I know in rural areas.
Maybe we each have to pick our poison.
