Actually I think cockroach is a better description of how they act than migrant.
Why don’t we point the finger at Mexico and ask them why their citizens can’t wait to get out....they ought to take better care of their own people - talk about the 1% - there’s a lot of money there concentrated and same with the other “migrant” countries. Why is the American middle class supposed to pay for their greedy 1%?
Democrats don’t see Mexico as a nation to be convinced to do anything. They see their citizens and those who transit through it from points farther south as a demographic voting bloc predisposed to voting Democrat. It is as simple as that.
A Democrat will hang onto their personal power and control and money as long as they can, and they will retire and go enjoy, their heirs and the rest of us be damned. The only example where I see the contrary to it is the Clintons and their foundation which is set up as a perpetual fountain of wealth, power and influence for the foreseeable future.
