I think one aspect of an answer to that is that they are less likely to have product-building skills, and also they are more likely to create or contribute to what you might call the shyster/shenanigans part of the economy (see Wall Street, the "Financial Crisis of 2008", etc.) rather than making real things people want in exchange for an honest price. Speaking in general terms, of course. Also, they are less likely to create some new innovation or breakthrough that gives the US a tech edge. Also, for a STEM person, it's generally easier for them to learn business and do the things truly needed in that area, than it is to go in the reverse direction. (Again, speaking in aggregate terms, and understanding there are always individual and exceptional cases in every direction.)
