Good to have immigrants in USA

I went to SSA(Social Security Administration Office) this morning with my friend for his work. I was reading through the manuals lying out there for everyone's understanding.

I was reading basics about Social Security. As you all know, Social Security System is mainly for retirement, but not just that it is more than that. The youngsters today will work for today's elderly people's pension. Today's elderly person had worked for yesterday's elderly person.

In the manuals, I read that 36 million of Americans are above 65+ age as on date. But in 2041, looks like the elderly people will be doubled, because of baby-boom problem. The young people on that day, will not be able to feed as much as these guys had contributed. So elderly people on 2041 will be abundant with less young folks, which is going to be a problem.

My answer for this problem would be - Just get as much non-immigrants possible from outside the country to get them pay the taxes more as on date and anytime. This will make sure at anytime they fill the gap of less youngsters in the country right??!!!

Your comments on the idea??!
