The 7.5% is not income tax - it's just salt-duty! If we were to add a 7.5% duty for salt alone to your current 50% tax burden, I'm sure you'd be marching too.
Suspect the average early twentieth century Indian farmer would kill for the OP's state subsidised education, healthcare, unemployment benefits and pension too, never mind his disposable income after tax...
No, I mean that my income, capital-gains, sales & property taxes, along with fees like those for my car registration, equal roughly half my total income.
I wouldn't say that sales tax is a large burden, but 8½% adds up over time.
No, I spend less than I earn, and save quite a bit. Some of that savings is tax-advantaged, but overall I pay a huge amount of my income in taxes & fees. I don't mind that taxes exist, really; I don't mind paying for a social safety net. But I think something's wrong when half of my productive labour & investment income is taken from me every year.
Maybe, but your 50% left cover your expenses for food, clothing, shelter, medicine, etc. I doubt that the 93% the average Indian laborer or farmer had covered his basic necessities. And as another posted said, this was just the salt tax.
