> Germany has the highest number of billionaires in Europe.

It is better to use number of billionaires per capita. That would be: Monaco, Liechtenstein, Guernsey, Cyprus, Switzerland, Sweden.

    > Those contributing the worst to wealth inequality are paying minuscule taxes through family offices

I did some Googling. It looks like they are using Familienstiftungen (family foundations). They pay much lower taxes than regular income tax. Yeah, I am with you on this one: It is bullshit that they can pay lower taxes.

One thing that I wish more countries did to handle large inheritances: Make people pay a relatively high inhertiance tax (say 25-50%), but grant them a state-backed low interest loan to repay the inheritance tax over 15-30 years. My hottest take: Make there almost no exemptions (farms, family homes, etc.) and no minimum. Any well-run, but private business, should easily be able to pay this back within the timeframe. Also, it would protect family-owned businesses, which I know is an important cultural consideration in Germany, thanks to Mittelstand.
