If it is business as usual then nothing has been done to arrest disabilities uncontrolled growth. Uncontrolled growth means that the disabled will still be dependent upon government. This may mean more and more money. More money may lead to resentment. If we are resented then what happened over 50 years age could happen again.
Progressivism is the last political ideology.
It is a type of liberalism but it is a liberalism which looks to long tern solutions. Its advocates see the problems and set out to rectify them. They pass laws designed to eradicate them or at least lessen their impact. Progressive ideas would mean that leaders would pass laws designed to curb disabilities growth. Curbed growth could mean that disability could cease to be a problem.
