I don't think it's ever been
easy to get into the US. A tour through Ellis Island will tell you as much. The difference is that, in the past, the US
needed its immigrants. They built its cities and its railroads and much of the US's early industry. Later the US's immigrants were its main source of scientific advancements...but the US's relationship with its immigrants has, I think, always been strained.
The difference is that, today, there seems to have been a shift in attitude. The US no longer thinks that it needs its immigrants. On top of that, the world is a different place today. No longer is "the American dream" unique to America. I know many people who've started businesses and found great success elsewhere in the world.
It may be cliche to say, but only time will tell if the US's new attitude toward immigrants is justified or will prove its undoing. In the mean time, the world is a great big place with many wonderful things to see and people to meet. I don't think you'll miss much if you never go back...
