If the rich have got richer then the poor should be jumping up and down with huge smiles as they will benefit. We will have the funds to keep paying for them to live without working and the like.
Well, no they won't. Unequal societies are generally unhappy societies and score poorly on a number of quality of life indicators.
You can't escape the fact that at any one given time, there is a finite amount of money going around. If you make tax less progressive, more money will be taken from the rich. If you don't have strong employer protections, the rich may get richer, but the poorer will suffer job insecurity and lower wages. If you privatize essential public services, the rich providers may get rich from exploiting needed services where demand is inelastic and there is poor or no competition, but the poor will suffer from higher prices.
The 'trickle-down' theory is nonsense, and has been shown to be nonsense over and over again. The rich don't spend their wealth the way the poor do. They hoard it and invest it in non-productive financial tools. The poor and middle-class, on the other hand, will spend all or most of their income on essential living costs.
Nobody has an appetite for destructive Thatcherite policies anymore, Xenia, except for a few Tory sociopaths. You're fooling no one.
