As I've commented previously: https://news.ycombinator.com/item?id=46257889 "I am calling for a temporary moratorium for issuing new worker visas based on the current economic macro and existing immigrant worker base in the US companies can pick from, yes. I support the current $100k H-1B fee, in perpetuity. The domestic workforce exists, it is a choice to not pick from the domestic labor pool. Choices have consequences."
The US has an obligation to its citizens, not corporations, not immigrant labor (already on US soil, or desiring to be on US soil). Shareholder returns go to the top 10% of Americans (who own 90% of US equities), so any argument about prosperity impairment from impaired immigration is going to fall on deaf ears in this context. Again, we may disagree on this, but I think I can find a majority of Americans who do agree with this sentiment (considering the current macro and affordability crisis in the US).
