Just got this news in on SKY, in relation to post 1.
"Research by the Organisation for Economic Co-operation and Development (OECD) showed the wealthiest 10% of the population in Britain earns nearly 12 times what the poorest 10% earns - and it is still rising."
So in the UK the gap is 12 to 1 and not 10 to 1.
That the gap is rising should be food for thought. My view is, that these characters increase their own wages so as to get the tax back wich they pay.
Example: I earn £200.000 a year and pay £100.000 of it on tax. So I give myself 100% pay-rise, earn £400.000 a year, pay £200.000 tax.
Result: I have 200.000 net earnings.
Outcome: I effectively paid no tax!
(But for how long?)
