This tax rates graph is insane and probably the best depiction of "how this show went to shit, slowly" I have ever seen.
Looking at it, to me the 1960s/70s had a "healthy" taxation. But thats only me looking at numbers and sensing some kind of fairness. But I might be mistaken.
I tried comparing the graph to the current german situation but I am not able to find a similar one. The only one I could find that gives similar data is this one:
Which looks at the amount of income tax one pays depending on whether they are married (Ehepaar) or single and how much relative to the average income the household earns.
It doesn't look like much but I find it hard to compare them really.
The highest earners have to pay around 45%, which this also dropped over the years, from 53%.
What would you think would be a reasonable taxation scheme to "make it work"=
