My question.... If the government could find utilizations on the citizens for taxations on generating funds for infrastructures and other government services , why don't they invest on the citizens or support those with the potentials to productiveness knowing quite well that once they makes success, they would be demanded to also contributed to the growing structures of the economy?
What the government knows is that if a successful individual refuses to comply with the government order, they will get you frustrated tending to fold your productiveness qualities or you go to jail.
What kind of support you are expecting from the government? They have built collages so that you can study. Many government collages are nearly free for the citizens. Same goes for government schools as well. In my country, the basic education up to 5th standard is available for free. Many other facilities are also available for nearly free of cost. That's the support government should provide to their citizens. What other support you are referring to?
Also do you think that "individual income tax" is the only tax you pay? try to find the data for your country and you will see that the "individual income tax" probably contributes around 2% - 4% of the total taxes collected by the government. Citizens pay indirect taxes for every purchase. That's where the burden is!
So, why don't they tax the poor who barely struggle to eat?:Simply because they found those set of citizens useless and the prison will be occupied if charge them for not paying taxes since there are more Poor people than the rich in the society.
People who can barely afford food, how would they pay taxes? Ask yourself!
