Universal Credit is actually just an extremely expensive and worthless type of income protection policy so just another a type of regressive tax.
There’s only so much of all the different types of such taxes from council tax to VAT and road fuel duty that the economy can stand.
Especially in an economy based minimising wage levels by maximising labour supply and maximising imports.
While exporting/squandering resources like oil and gas if not trying to put them beyond use in favour of expensive dangerous options like nuclear electric.
Lions led by donkeys indeed.
