I agree on the 33% but I also do not think that someone making 40K should pay a higher percentage of their income than a person making 10 million.
Where does this happen? Where does someone making 40K pay a higher percentage of their income than someone making $10 million? But why should someone making $10 million have to pay a higher percentage of their salary than someone making $40K?
Is it fair that someone making $40K pay a higher percentage of their income on food, housing, gas, electricity, cars, Christmas presents, etc...?
