thunder after lightning
As you are accurately concerned and worried about, and as the Roadmap to the 21st Century predicts, borders are going to bend and there will be threats to national sovereignty but borders and sovereignty will prevail. OTOH, the only other options, those that you advocate, leads to a withering of the economy which results in a loss of equity. A certain destruction of the nation.
You are correct about the unions and McK but you are ignoring the unions opposition to guest workers/the Bush Plan.
Your, and many other's, problem is that your knowledge and perception on this issue is short-lived. The long-running debate is the pubs wanting temporary visas and the dems wanting permenant visas. You can trace this back to the Braceros and LBJ killing that program to benefit the unions. This was followed by the creation of the union with no members(UFW) and how the dems were able to prevent the expansion and evolvement of the H2A and H2B.
Your also ignoring who holds the power in Congress. Twenty years ago it was the Senate republicans telling Reagan that this was the best deal that they could negotiate so just shut up and sign it.
Then the power began to shift in the 90s and although the pubs could not prevail, they were willing to walk away from the table on the correct assumption that their power would further expand in the near future and they would soon be able to dictate to the dems. In the meantime the illegals would take up the slack.
But what the pubs didn't percieve was the split. That hairline crack that occurred in 99 is now big enough to drive a truck thru. Consequently, the dems still hold the power. You can rant all you wantabout the Bush Plan but it is still DOA.
