The Government highly relies on the middle-class tax payers for the money and most of the taxes collected in the form of indirect taxes so that people may not actually aware that they are paying taxes for everything from their salary, fuel, medicine, anything everything has taxes that eat most our earnings.
So as a result we are paying from 10% to over 50% of our earnings just in the form of taxes in one or another way. So one who really wants to achieve financial independence should find a way to reduce their tax pay legally like how the businessmen do.
Or like the bald guy says, we need to find a way to exit the Matrix.

Government relies on the tax of every citizen in the country and not just just from the middle class. Perhaps not only the rich man or the business men that knows how to avoid tax by some loop holes in the system. Even the middle class too who gets to knows the loop holes to avoid taxation are doing it and skipping to pay some tax. Businesses starting from Partnerships, Corporations, sole proprietorships and limited liability companies are paying tax and still paying their employees who also in turn pay tax. You can see that tax is coming from everyone in th country. If one person can avoid tax through any means, another person that knows the same means can also avoid tax too.
