The rich have to much money.
There are many uses for that money, more than 20% of the USA's money belongs to the rich(1% of the population). That money has many more uses that for their leisure. Many are in the streets in poverty while the rich make money. Do the rich need all this money? No. Some may ask, do we have the right to take off the rich, yes! They took money off us. With flat tax, everyone has to pay an equal amount, it suits the rich, but many will not be able to afford it. Proggresive tax is much better. It allows everyone to be taxed according to their income. Much fairer!
