This is the part that really gets my cogs turning when people mistakenly think that we (the public) 100% fund the royal family. It is when you read into things a lot more complex than the government just "writing a blank cheque" so to speak. There is land throughout the country which is owned by the crown, this is farmed and lived on by regular people which provides a lot of income, as well as the income from all the stately homes. Many of the "minor" royals have there own business's which provide them their own income. There is also the money that the Royals donate to charity, I would need to go research this but I am pretty sure that they donate more money to charity per year , than they receive from the government.
