You seem to be assuming that el Bunko is doing this for something other than money. Look at the list of "contributors" to his East Wing destruction: Apple, nVidia, Oracle, etc. They are all big tech companies and they all love H1-Bs. I don't know if el Bunko is paying them back or doing it in expectation of future contributions to his whims (most importantly his wealth). My guess is both. Why H1-Bs? Because he wants whatever he wants NOW, he doesn't give a flying rat's ass about investing in the future like increasing money available for education. That would take planning and implementation that takes years, nothing he is good at (is he good at anything beyond collecting rent by shaking down people lower on power curve than he?); his attention span is akin to a gnat's and so he cannot fathom it.
As usual with el Bunko, when in doubt, set the Grift-O-Meter bar as low as you can and he'll find a way to limbo under it. And never forget that those in his "businesses" widely admit he cannot read a balance sheet. That explains his bankruptcies (how does one bankrupt casinos? Who knows but he found a way.) It also explains him honking on about how he's collected over $19 Trillion in tariffs. If you do not understand the ludicrousness of that number, you missed the last 50 years, go back and start over.
