Christ. Entitlement isn't the word.
Of course it shouldn't be lowered. People who need UC now are no more special than those who needed it last year.
If you have the means to support yourself during tough times then do it. If that means dipping into your £000's of savings then that sucks - the same as it did for people before this crisis. But it's not a bottomless pit of money.
Personally I think being able to have £16k of cash in an account and STILL be claiming benefits is VERY generous.
