Not radical changes but just expect some common sense being applied.
Over the last decade housing prices has doubled and the city receives a small percentage for each transactions. However this money did benefit only for the whole community but rather for clientlism. Debt has been getting higher and so the taxes. Driving has been made impossible and restaurants are too expensing for the similar service and quality you can get in London ( where I live now). Even the nightlife has been restricted
Paris is becoming a big sleepy museum where only real Parisians do appreciate the lifestyle.
Again I more disappointed here by the lack original idea And innovation promised by the candidate not by the mathematician. If you look at what the current mayor propose and you will find nothing that different.
However I'm sure you will enjoy your Parisian experience, despite all the inconvenience, Paris is still a beautiful city.
