It is not "Nazi" germany , but rather than the economical management / problems that Germany has in 1937-8, and China facing now.
At 1930 Germany has high unemployment and underutilisation, it was solved by starting a big armament program and running war time like economical management.
This solved the prroblem of excess unemplyoment, and generated 8-10% growth for a decade, but around 1937 they moped up the unemployed, the low utilisedworkforce (from gariculture and so on) and they faced stagnating perfomrance ( means they reached the maximum level of peace time military porcution) , growing wages, and workforce shortage.
At that point they had the choice to wound down the military production, and simply rebalance the economy to consumption from investment/military production, or hit the wall,and be forced to do the same.
The situation is similar in china, appart from the investment in China is not weapon making industry, but roads, buildings, infrastructure and factories to make all of these.
And the economy growth in the past decade(s) was mainly the growth of the capability to make more of the above.
Now the next step can be to wound down the excess capacities,send into bankrupcy many companies, BUT protect the workers and consumers , and pushing under the bus the goverment officials and business owners/ management.
Or just try to go forward this road, and face labour shortag.
China managed to do all of this due to the tight control of the goverment above the economy like in Germany in the 30s.
But at sam point you have to pass the control to the consumers.
Your fantasy is not working.
