When you are leading manufacturing power in region and loosing markets to China while allowing external powers to destroy your energy supplies(banning nuclear and blowing Nord Stream 2).
No political bullshit will help with objective reality, being it rightoids who promise "optimizing" social spendings(while leaching on corruption) or leftoids who want to tax the rich(which will just drive factories and businesses to Poland/China/etc).
You could end the practice of land rent. This would encourage productive activity instead of treading economic water.
The destruction of Northstream 2 had no effect at all on the energy supply to Germany. The remaining capacity to Russia was never used over 50%, if that. Considering Russia intentionally drove up prices in the months leading up to the invasion and even rented storage capacity to keep it empty to better blackmail, there never was a sane argument for keeping the gas imports from Russia going.
