One century's worth of medical advances and evil liberal agendas like "free healthcare" and here we are in the 22nd century able to cure darn near anything. Will there still be a welfare system? Hard to sit on your ass when there's nothing wrong with it??
In 100 years don't be surprised if humanity (at least the West) has all but condemned working all together. Robots and illegal immigrates will have all of the jobs in 2113.
