I don't know what you personally want from Mexico, but the US wants Mexico's cheap labor. Doesn't matter if that labor is on US soil or Mexican soil.

The willinginess to clean hot tubs and hotel rooms, to hang drywall and polish walmart floors for minimum wage or less.

and they want our medical care and education system, so when you look at the tax costs - the labor isn't really that cheap when they are on our soil.

that is NOT a positive.

But it IS cheap for the employer who sees the short term gain with no regard to the larger context.

What about the jerk that passes on the shoulder? All the cars are going in the same direction, all the cars contributed to the construction costs of the road, (and to the traffic) but because t works for the lawbreaker, but only because the lawbreakers are in the minority. If we all spread out the balance of the traffic jam onto the shoulder lane, then everyone would still be in the same slow traffic. And although the lawbreaker doesn't realize it, he's working against his own best interests, albeit, long term or low probility interests. For example, his travel in this breakdown lane could hinder emergency services traffic. What if a tow truck is trying to use the lane to remove the cause of the traffic jam?

Well, that's just a lot of blather. Anyway, I believe the lawbreakers take advantage of short term advantages at the cost of the greater good for all.
