Reply #105: Current progressive scale problem

[M155Y_A1CH]

If your income progresses one dollar into the next tax bracket you will be billed an additional 5% on all of your earnings. Where do you set the progressions in percentage of tax so that it would be more fair if you don't know how the individual will truely profit from that income? You have to use arbitrary cut off points to decide. A dollar to you may mean more or less to me.
