first off, your talking ancient history compared to the issue at hand.
every citizen of those states know that the area they lived in was once controlled by mexico. does that mean that we should be paying them for the privilage of living here?
there was a time when there was not enough americans to do the work we needed. that time has long since passed. does that mean we own people that did not have any connection to those who came, and settled here afterwords, a living at the expense of the decendants of those who helped build this country?
the quote was directed at someone who said that no american wants those jobs. as someone who would gladly have done those jobs at one point, that statement was highly laughable. I dont need theory to support the knowledge that people that come here willing to take half the minimum living wage are takeing away money from those who expect to be able to put food in their families mouth. those illegal immergrants are sending the money to mexico where the cost of putting food and shelter for the family is a small fraction of what it is for those who live in this country. should we starve our children and let them die of easily cured diseases so that we can take the same illegal wages as these people are doing?
your statement shows that you have not the slightest understanding of the situation, yet you are there lecturing me on how bad i am expecting to have a chance to live in my own country, without someone else taking all the jobs and money out of this country because 200 years ago the predecessor of that goverment had control over this area.
