My topic would be peace and saving the climate. And to achieve both goals, you could even get all the unemployed off the streets and out of ALG I and citizens' benefits and use the money saved to improve the infrastructure and subsidize pensions.
Road construction would be saved in the same way as the construction industry and both retail and wholesale trade, and people would be working at full capacity and therefore more relaxed and satisfied, but they would and should be happy to work 10 hours a day, thereby increasing GDP and finally getting the German economy back on track and swinging again.
In addition, targeted immigration could also save the care sector, hospitals and many other industries by only allowing skilled and capable workers to immigrate to the country.
Ultimately, both far left and extreme right parties would disappear again as people would be able to look to the future with more hope and sleep better without the stress of the media, which would then run out of food.
