Austrians and Progressive Taxation

Hello, I was reading “The Austrian School of Economics” by Eugen-Maria Schulak today and saw that Bohm-Bawerk was a proponent of a progressive tax code along with other early Austrian economists. I am just wondering what the current consensus among Austrians is on a progressive tax code.

Thanks

EDIT: i found this:

i took out references cause there were many many of those symbols in there

I love to tell this story:

So the first Mont Pelerin meeting had economists such as Milton Friedman, FA Hayek, Ludwig von Mises, George Stigler, and a few others, talking about distribution of wealth and whether a progressive income tax was justififed. Some of those ecoonomists were claiming that there might be a justification for a progressive income tax. Mises stood up and said," You all are a bunch of socialists," and walked out the door.

So generally speaking, Austrians do not like the progressive tax system. ( maybe it is better to say that liberal minded Austrians do not like the progressive tax system.)
