In this country that’s not the problem. The fraudulent claim rate is currently about 0.7%, but many people who are legally entitled to benefits aren’t getting them, because the rate of fraud by the private company in charge of assessment is extremely high. (The current medical assessment form declares you capable of movement, for example, if you can take two steps unaided - even if three steps would kill you.)
This is not a mistake; they were hired specifically in order to deny cover to the sick, disabled and injured. Our government has been embarking on a four-year-long campaign of slander and viciousness against anyone on benefits, including an officially-sponsored slave labour program for the unemployed.
