I have no doubt it's hard work. But it seems there are plenty of people willing to do it, so I value it at whatever the market pays for it.
I am indeed sitting at a desk, but the market seems to value what I do (which sometimes involves working for 80 hours a week) more highly, even if you dismiss me as a "desk jockey."
And there's no guarantee that immigrants will be inferior to American workers. The random illegal you hire off the street is probably not particularly qualified, but I've talked to businessmen who find too many American workers--particularly union workers--lazy and entitled, and immigrants generally much harder workers.
I am glad you have talked to “American businessmen”...no doubt they are the very ones using these illterate ( yes illeterate because they can’t speak or read English and the manuals and NOTAMS and all other FAA notcies and heads up are in ENGLISH).
Just as Phillipino ‘nurses’ and most foreign doctors are not qualified ( and are under trained and shouldn’t be allowed to even sit for boards here) and really provide lousy care and dangerous care.
Those “plenty of people willing” have also built crappy house that are falling off the foundations and the walls are crumbling.
And ooooh boy 80 hours a week ( either an attorney or maybe a stock broker) as if other folks don’t work that hard ( and harder) too. You provide no service and no value for the market but no doubt you have “helped” us all by being so very market driven
