There is definitely animosity towards migrants in the U.S. but I’m not convinced it’s any worse than in any other country with a large immigrant population. Look at the huge advances made recently by far-right parties in Europe for example, or the riots in England.
> lack of reasonable immigration paths for professionals
getting a visa is the hardest part, but doable if you’re a bit lucky. Once you have the visa, getting permanent residency after a few years and ultimately citizenship is relatively straightforward, IF you’re not from one of a few countries with large numbers of immigrants to the U.S.: mainly Mexico, the Philippines, China and India.
It seems from your profile that you’re Mexican so yeah, getting permanent status in the U.S. would take a really long time even if you got a visa.
This is one of the biggest competitive disadvantages of the U.S. currently: making it unreasonably hard for skilled people to immigrate, compared to places like Canada or Europe. But I think it’s an exaggeration to say there’s no reasonable path.
