Communism in Hungary was introduced and kept up by Soviets after the 2nd ww. The very considerable difference between Orban and Kadar (the longest serving communist leader) is that Kadar paid attention not to make his direct family and direct friend the most exorbitantly rich guys in 15 years, which probably also made lots of mid-income people poorer in Hungary. And despite very strong democratic backsliding in many areas, it is still more democratic than during Soviet-led times. But that's probably not due to Mr Orban's character or self-restraint.
Baumgartner's idea is probably related to fashionable libertarian ideas of those rich people who never had the patience to feel sympathy for other people, nor to study history or humanities, but feel like they should have a say.
