I would introduce a Nationwide program for training entrepreneurs. How to deal with the beaurocracy France has towards small business. I would also cut the tax burden for companies employing up to 50 people.
The growth of a small business is very difficult. Funding expansion is a nightmare, added to this the attitude the French have towards employers it's no wonder the employment and economy have stagnated.
There is no point retiring in France at 60. You are not able to do any further work of any kind past official retirement. Planning for that retirement in France is not something most people in France can afford. There should be a provision to do part time when someone reaches retirement age. Even 10 hours a week can be enough to help retirees live more comfortably. Also not everyone wants to give up work.
president Macron would have been my choice too. Just don't let him get away with being a glossy toy boy with no real substance. Also don't let him get ruled by his wife's strategic politics like Billy Clinton.
