This is not a logical issue. It's an emotional one. So, it depends on the person. Wouldn't you held anything against a country if that's country's border control detained you, denied the services you paid for, denied the properties you have in the country, treated you like a sub-human? Would you try to enter that country again? Try, just try to be empathetic...
It's also a financial and practical issue. Being refused entry at the border can mean significant costs in non-refundable bookings and re-booking of flights. Not to mention the fact that you just wasted some very valuable vacation days (which to many people are worth more than the money they represent).
I know I don't want to waste my vacation days playing bureaucratic Russian roulette when I could spend them in any one of the dozens countries that will happily let me visit with a minimum of fuss.
There is no doubt that the U.S. immigration system is broken and needs fixing, this is a complicated political issue that is currently being debated in Congress. Conditional on this unfortunate reality, which we can't immediately change, my advice is not to over-react.
Don't deflect blame onto the system, either. I will accept many excuses for many job choices. I will not accept any excuses for being paid to do this kind of evil. If their behavior were mandated by immigration law (and it's not), they would still be 100% culpable.
True, but the onerous nature of the experience has impacted the popularity of the US as a tourist destination.
"The United States' share of the total travel market is down, to 11.2 percent in 2010 from 17.3 percent in 2000"
"There were also big declines in the same period in travel from France (down 23.2 percent), Brazil (down 20.3 percent), Germany (down 19.2 percent) and Japan (down 5.8 percent)."
