Why don't they stop cutting money from the people,and get from the banks?

If the money is in the banks,why don't the Tories stop cutting money from the people and instead take it from the banks.The bonus they give the banks is much more than the amount they will take from the cuts they are doing.if the government has no money, they should stop giving bonuses to banks and start taking the money from the banks and invest on the welfare system(Health care,food, accommodation and education).The money they will get from the cuts will not be saved,they will put it in their pockets and spend on their lavish life styles buying ponds for their ducks ,not much different than the banks that take the money from bonuses and make big party for the bankers.
