For HP BSM training, our corporate trainer flew all the way from Paris, France to New Jersey, USA. At lunch we were talking about how was the market for performance engineers in France and Europe.
During this discussion he informed that how the wages were quite high in Switzerland, but taxes were high too, many professionals chose to work in Switzerland but live in France, that would save them on taxes, as taxes in France were comparatively less. This choice of working in Switzerland and living in France has led to a high demand in real estate at the French border adjacent to Switzerland.
