Idk wtf you’re trying to say but you sound like a crazy person.
It's no problem if you don't understand the difference between what it means for a tax system to be progressive or regressive versus a tax system that has different marginal rates.
For example, a sales tax (especially in Kansas), is considered regressive even though it is implemented at a constant rate. This is because lower-income households spend a higher percentage of their income.
The term progressive when it comes to taxes only refers to whether or not higher-income groups pay a higher percentage of their income in taxes compared to lower income groups. One way to implement a progressive tax system is with higher marginal tax rates. However, for a tax to be progressive, it does have to have higher marginal tax rates. The higher rates could be global and apply to all income including income that is below the threshold for the higher rate.
