Most important thing was H-1B Visas, and immigrants were able to come here through those, and find a loophole around them by having children and thereby claimed citizenship, working with the organizations they traveled for to do so, so the organizations don't have to pay them jack shit compared to the actual workers. Obama, for years, let this slide, knew about it, and failed to address it. Said immigrants worked in IT. Once the huge wave of immigrants came in, my dad, who also worked in IT, lost his high paying jobs to these immigrants who were trained, and took his position with half the pay. Family went from the literal top 1% in wealth to near-lower middle class, and we still are now. Since 2008 we had to move 4 times to find cheaper and cheaper housing. And goddamn 10 years since then every time I see an immigrant who can barely speak English driving a Lexus or a Maserati I internally cringe.
Not only that, throughout his speeches, he implied lots of progressive and feminist rhetoric, which I strongly dislike, because he gave more verbal empowerment to women, who have already had double standards since the 70s.
