It's interesting your concern for these small businesses, nary a word for the taxpayers.
Cleaning up (dissolving) the mex govt. would solve everyones problems. Your side never brings that up.
Every day, huge numbers of mexicans legally enter the US and spend a huge amount of money. Fron Brownsville to San Diego.
The MMP, in their effort to close the border, have intimidated the mexican buyers and they are not coming to spend money.
Many here want to close the entire border. The loss of cross-border commerce from such an action would be devastating to US businesses.
