Government tax about an bank money

Lets say about yuo have an Account, when you open it was with 100, at 10 years ago, today you have 2000,oo an exemple, yuo gonna receive in the end of the year 40,00 the tax of the government is only about 40,00 and not 2040,oo if see if the Government collect about all the 2040,00 see that the Governmetn gonna receive for money that he taxed in others years, yuo receive in the first year 0,30 and the Government taxed, in the second year yuo receive about 100,30 that are in the bank 0,40 see the government already taxed 0,30 if the Government taxed all the Governmetn will be taxing the money that you started and already was taxed and will taxing again the same 0,30 of the previous year and now the 0,40 the Government can't tax with income tax 2 times the same fact, fact you receive money 2012, in 2013 the Government can't tax again you have receive incomes in 2012, this also is if you have a house a house could not giving any income so you are bleading in other place to pay something that you don't owe, so sometimes is better a lawyer to explain you the law to a counter if this one isn't understanding the law, if you tremedous rich a lawyer that is specialized in Governamental tax could keep yuo so rich that is the same that you be 30 times richier.
