You are assuming remote people are OK with being second or third class employees. I'm not sure how long this is going to be true in the post covid world.

They're going to be 'employees'.
Now - they will be paid less - yes (maybe that's what you meant?)
But that's a function of supply and demand.
They will absolutely accept 'less' because it's where they sit on the supply/demand curve.
I'm not holding my breath over the situation changing in the near future, but 2 years of remote work do make people reconsider things.
Companies are not 'discriminating' against people in other countries due to 'lack of legal protection'. They are just hiring people in other countries, and paying them what they are worth.
That's it.
It's 100% supply and demand.
There are good and bad developers everywhere, and cost of living and opportunities are different everywhere.
Supply and Demand will work itself out.
However, tech salaries in the US are much higher than tech salaries in Europe even after adjusting for cost-of-living. That is what leads to resentment: a developer in London making a London salary would not be able to afford the same things as a developer in New York making a New York salary.
