Complete and utter anti-Semitic horse shit: my dad was prohibited from as much as leaving the Soviet Union to attend a scientific conference until 1989. Even so, he still did not want to leave the USSR or the post-USSR state until it was clear (after Soviet Union's collapse) that economic opportunities for our family were much better in the US (we finally moved in 1996).
Believe it or not, leaving everything behind and immigrating to a country with a completely different economic and political system, a different language, and often a need to work in a completely different industry is hard and often the last resort. My dad researched mathematics at a university in USSR, but that was simply not an option for him in US -- he ended working as a grossly underpaid engineering manager in a startup; yet he was lucky -- friend's dad had a Ph.D. in Economics, but ended up doing menial labour and later started a moving company. Going from masters/Ph.D. and "intelligentsia" to menial or clerical labour was the rule for immigrants, not the exception.

Except that while university education in USSR was cheap, it was not actually completely free: you could receive a stipend to help (if you qualify), but it was not guaranteed.
All Ivy Leagues provide need-based scholarships. Top-tier public universities can be extremely cheap (e.g., UT Austin) and many offer full-ride scholarships. Getting a STEM degree free of charge is very well possible in the United States.
Not to the mention, the idea that if a state pays for someone's education they subsequently own them is quite repugnant.
