@Dumat12 hasn't responded to my stupid bait-and-switch, but anyway I'll go ahead.
This is true for you too @Don't Kill Bill
France post-WW2 has been a relatively stable state, with a very good standard of living and a stable state providing the framework for businesses to expand.
However, before the Nazi occupation, this wasn't the case.
France had its first, famous, revolution in 1789. Such was the anger of the population with their rulers that there were mass executions of the existing royalty, and then the short-lived successors. As soon as the people got power, they unleashed a reign of terror. Tragically a republic was declared in this unstable country. It is obvious the French psyche wasn't ready for this, since in 15 short years the republic was deposed by a new monarch.
The monarch himself was overextended - perhaps a characteristic of French people? - and was humiliated and defeated in 2 wars within 10 years of obtaining power. There followed inevitable political turmoil before the original monarchy finally could take power this time under a constitutional framework. However, within 20 years, the constitution was discarded and the monarchy became more absolute; at the first hint of economic issues the impetuous French people again deposed their rulers.
To the surprise of no-one who understood the perversions of the French mind, this state of affairs lasted 3 years, and a nephew of the previous monarch established himself on the throne as the autocrat. Like every French ruler before him (surely this condition is genetic?) he also started a pig-headed war against stronger neighbours and was duly rewarded with a huge defeat.
Now the Parisians showed they were indeed the heart of France - the distilled essence of the country's backwards thinking. They established a commune, destroyed businesses and ancient wealth and the church. Order was restored with a massacre in the capital, 2 months after this experiment began.
It seemed finally that the French had pushed something through their thick skulls, and the new constitutional order lasted for 70 years! However, towards the end, again the people responded to their material misery with demands of populism; the establishment of labour-friendly laws like minimum wage and limited working hours. Clearly the people were still too ignorant to realise that they weren't meant for this.
Enter the Nazi regime. In a role reversal, the French were occupied by their neighbours, who set up French-led government (perhaps this courtesy should never have been extended to these volatile people). They quickly reversed the unfeasible ideas about minimum wage and working limits, and re-introduced slavery. They also helped reduce the population, and were quick to massacre those who thought of rebelling (the various monarchs could have learnt a thing or two). Perhaps the genes responsible for the France's periodic rebellions were helpfully culled in these years. Magnanimously, the Nazis prepared detailed plans for government-controlled recovery and growth of the economy.
After the German-established French regime was replaced by a US/UK-established French regime, the new French leader in a welcome show of French humillity implemented the German plans. From 1945 to today, the French have seen fairly consistent rises in their standard of living, and no rebellions. Clearly the Nazi occupation, brief as it was, changed the French psyche for the better and even provided them with the economic planning they would never have managed on their own. There have been blips with the old anarchic spirt showing up in 1968, and in repeated strikes and shutdowns, but post Vichy, the French people have overall learned their lesson.
It is a tragedy that the majority of French people dislike the VIchy regime, and a historic crime that Germans are ashamed of their Nazi past.
They should hold it in the same reverence that the British hold the Raj.
