I think one of the fundamental problem with h1b is that it is labeled as "non-immigrant" whereas for all practical purposes it is really an immigrant visa. Why would a person who is supposedly having rare skills come to a country and spend their best years here without reasonable guarantee of permanency? People buy homes because it is a reasonable belief that they are going to be living here permanently and it has historically been true.
In any case I don't see the point you are making. Should America be treating immigrants poorly because whichever country you're in makes you slightly uncomfortable to buy a home there? It's not an excuse for all this pain and cruelty. America should hold itself to higher standards.

I agree with your overall point but the answer here is money. The earning potential in the US vs. e.g. India is drastic.
It's not really money. Frankly, no 20 year old thinks that much about money. They do things that they like, whether that is going to school, working at a job, or starting up. And you don't know about the broken immigration system from the outside. The reason this problem is unique to India is due to country caps/DEI which prevents people from India on H-1B from getting a green card.
