When a person works and earns an income he is taxed on his earnings.
As soon as he starts spending his earnings he is again taxed by paying VAT or extra charges on the goods which are put in place to cover the sellers tax.
The money which has now been transfered to the other person is again taxed as income and again taxed when it is spent.
The cycle goes on. Tax after tax after tax. It seems as though we are slaves; drones, just feeding and feeding and feeding the system.
