So what's the solution to improving your experience, pay less in taxes or more? Don't add conditions. Remember that this is the subject: "So we get to work for the state about half the time (including VAT etc)".
Sidenote, as to your experience: most of that is not due to the German government, but to wars started by Russia and the US/Israel, and indeed other global crises. They have influence over how to act on crises, but they can't (for instance) magically make natural gas/oil appear out of thin air. The easy proof for this is that many, many, many countries with very different governments face those same issues.
