There are no special restrictions on anyone.
Our immigration system is based on sponsorship of close relatives, without regard to skills or wealth.

We must select immigrants based on useful skills in American economy or $10 million brought to invest in USA.

The quota system was abolished, but as you say, "family reunification" became a stated policy goal. This necessarily would contribute to increased immigration from places people are desperate to leave.

I do not believe immigration should be intended to alleviate someone's material discomfort.
