I don't understand why so many people take any criticism of the USA as a personal insult.

In many regards USA is a great country, in some/many regards it is not. Constructive criticism like from the parent comment would only make it even better.

It's not like the parent just criticized for the sake of criticizing. He also gave a proposal to improve the whole system. You can agree or disagree, maybe provide a better proposal, but this dismissal brings nothing to the discussion.

I didn't take it as an insult. I truly want other people to not want to come here. The downward pressure on IT salaries is impacting all other sectors of the economy and denying people here access to the economic ladder.

Canada wants to keep their wages low, that's why their immigration is so wide open. If it wasn't mostly Arctic tundra, they would be inundated with immigrants by now.

I'm just going to quote dang to you here:
