I find it astounding that in 2009, the total revenue from the income tax, at 6.4 per cent of GDP was almost identical to the revenue from social security receipts, at 6.3 per cent. If this were my country, I would find that scandalous, given the latter are so much more regressive (and job destroying) than the former. But it is not. I merely point it out.
