Yes, I fully agree.
So we need to find the right messaging.
I don't know about Germany, but here in the Netherlands most people identify as middle class.
So "stop taxing the middle class" and "let the billionaires pay more" is a message that should resonate.
I'm optimistic and I believe we will get there. The level of equality we have today would be unfathomable for somebody living before 1945.
The top 10% of income is not upper class. The error that people make, including you, is to focus on income.
People like Elon Musk have incomes smaller than $100K.
Upper class are the people who do not need to work and who live off of capital.
We need to shift our focus on wealth equality.
Look, the economy needs capital. If we want to be less dependent on the capital of rich people, then middle class people need to take over that role.
The people making $100-300K per year are key, because they can provide an alternative source of capital if their tax burden is lowered.
The people making $50K will not be able to provide large amounts of capital.
