Defining wealthy is hard, but people with discretionary spending ability. People who've got money in the bank.
I just wonder what kind of signals the market has been sending over the last 4-8 years that suddenly housing prices are going through the roof. Yes, lowered interest rates are one thing, but is there some wider indication that we're getting locked into a certain land use future? Like, the cities we've got now will only grow bigger, but new cities will likely not appear?
The coastal west is extremely popular, but in the grand scheme things, rather undeveloped. You could in theory have the entire coast of California be developed if you really wanted. I'm really surprised more states aren't eyeing "eff you" development plans like "hey we're going to build a new city in Nevada in Lamoille, deal with it." Add in high speed internet, cheap property, cheap taxes, a nice airport, and that area could support a decent population.
It just seems like everybody wants to live in the same place, and employers are only happy to oblige. If you want a job, you live near a populated place, and lucky for you, someone already thought of that and bought up all the vacant land which they'll sell to you for far too much, and now you need a higher wage, which will get pushed out to the customers in the middle of no-where with no jobs, who then need more welfare assistance to pay for the things they merely need to survive.
I'm still not entirely comfortable with the freedoms of land ownership. Too easy to be monopolistic. To easy to manipulate whole economies based on how much land (or housing) you own. It's no wonder that "company towns" were so popular in the past. You could control the cost of your product by paying your labor pennies because their housing was super cheap. I'm surprised Amazon and other big labor employers haven't gotten back into that.
