We have left our GenXers and Millennials quite an impending disaster. Our national debt is so large that even a 1% increase in interest rates creates a substantial increase in the annual deficit leading to increased debt. 2/3 of states and nearly every single large metro area has substantially underfunded public pensions so they will have to pay pensions out of taxes in real time or default on pensions. Medicare is already operating in the red as is SSI and SDI. SS will be in less than 10 years. Add to that the coming technology advances that will make 20-40% of all jobs obsolete in 10 years. 
Maybe the last thing these generations need is a massive number of Latin American dropouts to support?? If economists were right, and any and all immigrants grow the economy, why have we experienced the worst decade of growth in history with a historically high number of foreign born "workers"??? It's almost as if education matters more than nationality!!
