If I read it correctly, only 140,000 "green cards" are handed out each year. That's less than Australia takes and we have ~15x less population.

That's also less than what France takes in. But I'm willing to bet there's illegal immigration to the US as well, and it's a sizeable quantity.

There's plenty of illegal immigration here, but the skilled workers among that population are far outnumbered by the laborers.
