Should everybody pay the same tax percentage?

Ms
Do you think it's fair for the tax rate to go up if you make more money?? Or should it just be one rate for all? Those who make more are still paying more if it's one percentage for all...so why should they have to pay a higher percentage on top of that?  I think one rate for all. What do you think?
Should the income tax rate be the same for all people regardless of class?
