I would be in favour of the two child benefit cap, except that without it children might starve. Until someone can solve that, I reluctantly oppose its abolition.
I would be in favour of ending overseas aid, except that without it, actual human beings in poorer countries will die and our soft power diminishes globally. Until someone can solve that, I reluctantly oppose its abolition.
I would like to pay less tax. But demand for public services is rising, and the proportion of those working in the population is diminishing as we age. Until someone can solve that, I reluctantly support paying more tax.
I would like to cut spending. But whilst it's easy to identify individuals who milk the system, it's almost impossible to identify actual spending that can be cut without serious and unpalatable consequences. Until someone solves that, I reluctantly support current spending levels.
