As a result, I can see programmers from Western and Northern Europe, who as of know may consider relocating to the US, change their mind and say "why bother". Any EU citizen will have easier time relocating to London/Berlin - two places in Europe where a lot of tech companies are located.

PG's point is that a lot of people from outside the US (including from Europe) currently would prefer relocating to the US but they have difficulty getting a visa. Long term more and more people would prefer the second best choice that's available to them.

"PG's point is that a lot of people from outside the US (including from Europe) currently would prefer relocating to the US but they have difficulty getting a visa"

No, from my reading of pg's point: Most of the top programmers live outside of the US, so we should make it easier to get them by changing immigration policy.

This is a good point. But finding out that your employer is so nasty that they use your visa status as a bargaining chip, can be even more inconvenient.

Nearly every company larger than 100 people optimizes for financial outcomes. That's amoral, not evil, don't confuse yourself.
