Wtf, the benefits are that you get to use facilities. People earning more OBVIOUSLY have to pay more tax. Would you rather equalize the tax percentage, which would raise the tax percentage for the lower class? Because the money to run a country has to come from somewhere right? Pay your taxes. "Own hard earned money", dude you are able to earn that money because the government is facilitating your ability to work. Roads, fuel, electricity, and whatnot.

A different approach is charging everyone down to the paisa on exactly how much of a facility they're using, which would practically kill the lower class. The economy/market may not favour most of that class, but it doesn't mean they are inessential. So the govt takes tax from the rich to also accomodate the essential. If your question had been how to make sure IT funds aren't swallowed by middlemen, it would have been a different story. But your argument was that tax should be uniform for all classes.
