If I read between the arrogance, sensationalism and smugness, a bit of what you say makes sense. For those that just switch off now (I am tempted) I will summarise below:
The better off do pay a lot of tax.
It is not productive to tax them more.. They are leaving the country in droves.
The economy is not run well (Past or present I am not sure)
Treat your citizens like crack addicts.
Maybe I got a bit wrong there, but here is my view without figures plucked from Bob from the pub.
The better paid in society do pay too much tax (especially if PAYE). Bordering on a ridiculous amount. We need to start linking the personal allowance bands with inflation again and I would scrap the over 100k and you start losing your allowance rule. If you are in 100-125k territory you lose an effective rate of 60% of your earnings on that amount. I actually feel if you can collect all the correct tax with no loopholes or fraud, we could even reduce the higher rates of taxation as more would be collected overall. It actually does encourage people to earn more and then put more back into the economy. We need to do it in a way that the whole country gets better off, so the rich don't get richer and the poor poorer.
I personally think it is counter productive to tax them more, but maybe close the loopholes for the self employed and corporations, before we raise taxes. I think Labour have surprisingly started well with trying to give benefits to those that need it and not attack the better off yet. There is no golden bullet to how to fix it.
