Everyone needs to pay the same percentage. I dont where you live, where you were born, your job, etc. People with more money should not pay more because they are lucky. People with less should not pay less because they are unlucky. I disagree with taxes at all, but jf there is going to be taxes everyone should pay the same percentage.
No matter how much they complain, most middle class citizens can afford the taxes they must pay. They just wish they could pay less so that they can buy more luxuries, like a family vacation or a new care. It's the lower class that needs less taxes because they can't afford to pay taxes and pay the bills and feed their family.
