What's the Big Deal with Immigration?

Well, LA students are walking out protesting immigration bill. I dunno where to side on this issue.

On one side, why labor can't move freeely, when money and goods can. National borders are not porous, they are becoming irrelevant. The H1B and offshoring trends is a good case study on this. During the internet boom, many IT professionals came here on H1B visas. To some local workers delight, in 2001, it H1B visa quota was slashed from 195,000 to 65,000. Guess what, many of these jobs went away to India with returning engineers who could not renew their H1-B's, giving rise to companies like Tata, Infosys and Wipro. (for more detailed narrative, read The World is Flat by Thomas Friedman). So I believe that it's only fair if labor mobility can match that of financial assets and products.

On the other hand, I don't want hard earned my tax money to be used by illegals who are not likely to pay tax and thus free-riding by using social security, medicare, and public schools system for free.

There must be an optimal solution to the problem, but it's not likely what politicians nor general public want to hear.
