Make - don't fall into the cliche of "make the bankers pay". They do via PAYE. Had you said "simplify international tax rules in partnership with other countries for internet based corporates so that they pay their fair share of tax " I'd have agreed with you
Look at the evidence - the top 1% now pay 27% of all income tax
Top half of households pay 78% of tax receipts
The basic rate of income tax has been 20% since 2008 and the higher rate has been 40% for longer than that. There have been additional rates introduced but they do not affect middle and low earners.
In 2010, the income tax personal allowance, which is the amount you are allowed to earn before paying any income tax, was £6,475. This year it is £11,500. That has clearly risen considerably faster than inflation, so for people paying the basic rate of income tax there has been a tax cut, while a higher proportion of low earners are not paying income tax at all.
The level of income at which people start paying the higher rate of income tax has not been rising as fast as the personal allowance, in fact it has fallen in some years since 2010, but only about 15% of income taxpayers pay higher rate, so they probably do not count as being low or middle earners.
