@Proton2: nope, not familiar with it.
It's very interesting, thanks!
Especially the links referenced, found this little gem;
Decreasing marginal taxes on income at the highest rates, led to a boom in economy. Who would have thought?
Next question would be, is the boom sustainable or just a temporairy effect?
I'm more of a flattax kinda guy, it seems the fairest to me.
