2016 - Immigration problems

If you can't understand why Trump HAS TO BUILD A WALL, watch this microcosm of the immigrant problem... After you watch some of this, the only viable western democracy answer, is to put a halt to ALL IMMIGRATION. Generosity in technically advanced countries, can only go so far,(50 years of building infrastructure for non-technical countries--technical countries can no longer pay a fair wage to its citizens, etc...).... AT some point, the generosity has to stop (funding runs out), and all the countries must start taking care of their own, the best they can.
