Rich people hate paying taxes. They especially hate it when their taxes are spent helping poor people. They feel that they are being robbed by the government. They dream of an ideal world with no taxes, no government, no minimum wage, no unemployment benefits, no socialized healthcare, where rich people would live in their mansions and poor people would serve them for scraps off their tables. They even have their own party. It pursues interests of the richest 10% of the population and fools another 40% into voting for them by using various deceptive practices.
Naturally, there’s a lot of demand for books, articles, theories, etc. that would justify why big government is bad and why taxes are bad.
When there’s demand, there’s supply. This book is an example of this supply.
