“Baby boomers” are reaching retirement age. There will be more people collecting Social Security checks, and fewer will be working. Many are concerned that the Social Security system might become insolvent. Several years ago, the media was full of predictions that the system could collapse soon. It did not, due to the economic boom. Indeed, the Social Security fund received extra cash from new employees, many of them immigrants – 11 million of them here illegally. By throwing illegal immigrants out of the country and building the wall to prevent the new ones from arriving, Americans would cut off a critical source of cash inflow into the Social Security fund. They would cut off the branch they are sitting on.
