That's not how it works.
You pay nothing on the first 9700€
You pay 14% on the money you make above that, that is 14% of ~17k€
You then pay 30% on the money above that, that is 30% of the extra 5k.

My example was for a system that doesn't work in that way but switches from 14% to 30% for all the income, and not only for the amount above the threshold.
Maybe I should have worded it better but I take the downvotes I got as a demonstration of my point, that it would be insane.
