People under the age of 22 can still be disabled. People who can't work, can't suddenly become fit to work. As a country, we need to protect people, instead of allowing certain loopholes and tax avoidance for the uber rich to become richer while demonising the vulnerable.
PIP payments are a life line. People with disabilities are less likely to be accepted to a job, and jobs are scarce either way, and some may have additional requirements to live.
