The cost of high unemployment can be unexpected: in the late 20s and early 30s, it led to a change of government in Germany.
However, if we went down Barry's road and reduced income tax on the rich and wealthy, and even on companies making reasonable profits, or on businesses in general, the Treasury would have no money left at all to pay unemployment benefits, housing benefits, and pensions would probably go through the bottom too, not to mention child benefits and other forms of essential benefits.
We'd end up in anarchy!
Fortunately the Government doesn't listen to Barry's mutterings
