Why do some people don't want foreigners to come to the USA, yet travel on vacation to foreign countries?

Just to reitereate this person's question:

Yes. Americans go there and spend money and then GO HOME. We don't sneak in illegally, live off of their government, steal, take jobs, and stay till they kick us out. It's TOTALLY different.

It is not that some people don't want foreigners to come to the US. It is that no country should be so overwhelmed by any one group as we are now in the US. We also have to support these people also since most of them have come for the welfare and the freebies. Also tourism in Mexico is way down and most likely will continue to go down.

Yeah, I think that is extremely hypocritical. I mean, I would take it as a compliment if foreigners came here. I mean, if the Mexicans want to come, then let them. If Americans do not want foriegners coming then help make conditions better in their countries or stop visiting other peoples'.

If anybody could go anywhere in the world, The entire population of the world would suddenly end up in North America. Right? Hmmm... It does not take much thinking to understand the immigration and travel poilices currently in place around the world.

Thats like saying since I enjoy a day at the beach, why don't I want my house filled with sand and salt water.
