Of the 64 million people in the UK there are around 40 million of working age. Over 30 million pay their income tax through PAYE. Discount those who are self employed and those who do not use PAYE for other reasons and the proportion of people working and paying tax is a massive 75%-80%. They provide labour in exchange for payment from a company and pay income tax on it. That is working for a living by anyone's definition. Do non of these exist?
