It's been that way for years. The Mexican government actually counts on those remittances and figures them into their budget. They have it good right now because they encourage their people to come here, take what they can and help Mexico. Many illegals here don't even want to become citizens. This is a temporary situation where they can come here, collect government aid while they work and get paid under the table. Many of them cram into one home, so expenses are little. They start sending money back home and after a while, they have enough to return home and live comfortably.
Obama is helping the government there encourage people to come here and swoop up the freebies. There are ads running south of the border, which basically tell the people there how easy it is to come here and greatly improve their lives by taking advantage of the American taxpayers. An invite to come and take, with the blessing of the federal government.
It's shameless. There is zero respect for the border by our own government and zero respect for the workers of America who foot the bill for the politicians' hair-brained ideas.
