Many people who get rich through investing in land are lucky, they're hustling for money and use that to buy land, they do it at the right time. That was their best decision, after that they don't really know how to multiply their money.
I don't see it's wrong only the rich can buy land, because that's the reality. Bill gates get rich from his business, not because he make money from buy and sell land.
Every other investment companies, buildings, even cryptocurrencies can increase in supply.But Land is fixed.
Not entirely correct, Bitcoin is fixed.
