Money does not fix the supply problem the parent comment pointed out (at least for fields that need multi year training).
Let’s say that tomorrow we need 1M nuclear physicists. How can money help? You still need to wait for the talent pipeline to divert.
Why are they needed in the USA, but not needed in their home country?
Fortunately such ridiculous hypotheticals have no correspondence to reality. Most every job can be easily trained or cross trained. Mathematicians make good physicists. Nor is there some foreign pipeline of a million physicists. Such ridiculous argument exist only to perpetuate the lie of a skills shortage and deny the wage shortage.
