> Despite being able to show 10 years of consistent working history with income far exceeding the minimum, because I didn’t have a job lined up in the US (who would, or could, in that scenario?) we had to ask my wife's elderly parents to sign affidavits of support to prove I wouldn’t become a "public charge".

This seems entirely reasonable. You had as much time as you could have liked to apply for jobs after deciding to try the USA. Fortunately you were able to take advantage of an alternative that didn’t require that.

I’m not really sure what you were going for writing that. You think 10 years working in country A should entitle you to a work permit from country B?

> nor do they only come from white or european countries.

Why should that matter? If country B decides to only allow white and / or Europeans to apply to live and work in country B, that is entirely fair. It’s not people-from-outside-country-B’s privilege to decide what country B does or doesn’t do.

Discrimination is a human right.
