Actually, it's not that far from the truth.
When you are paid, you pay PAYE and National Insurance. While you pay is sitting in the bank, the government are scraping a small percent of your interest off via the Bank of England.
Once you get your money out, you pay your bills, many of which have extra taxes on them.
With what you have left you buy other things, which you pay VAT on.
The worst part is that most of the taxes and NI you are paying are for RIGHT NOW, this very minute, not one penny of your own money will be left by the time you are 60+, and there aren't enough working people in Britain to support this generation when it retires. Basically, if you don't have a private pension, you are fu)(ored.
