They are making the middle class income people pay more of the percentage of their annual income than the people who are rich and earn a lot more income than that of the people in the middle class range, so the government should make them pay more. This is the view of many people. But the rich people are usually the ones that are benefitting the economy of the country, running businesses that will benefit the country's income and economy and the government probably does not want them to pay too much tax so that they won't complain and say that they are the people who contribute most to the country's economy but yet you are charging us so much.
