Among other things...sick of seeing this 43% figure
"We've just seen most of the financial system of the western world collapse from the error of lending the money to buy a house to people who cannot afford to buy a house"
No, you've seen the US crash because of the verging on fraud antics of the financial markets, including the infamous CDS. Ireland has crashed because of the verging on corrupt antics of lending money to property developers to build houses noone wanted or needed. Error, my backside. Fraud and gambling. IIRC, if you took all the mortgages in the UK, added them up, you wouldn't cover the potential losses made by selling,chopping up and reselling the same thing five, ten, twenty times.
As for the trick of lumping three separate things together (income tax, employee NI and employer NI) in order to "prove" that tax is too high then this is mathematical trickery. Why stop there? Why not chuck VAT in as it costs for heat, light, water, materials etc. Business rates on the office? Fuel duty? Company car tax? Go hog wild, on that basis, I'm sure we can get the "tax" up to about 125% of salary.
The employer pays NI. The employer doesn't pay the employees income tax, nor the employees NI. (It collects it, but doesn't pay it.) Trying to add them all together and come to some 43% figure claim is hugely disingenuous because they are separate things.
