It is not at all easy to obtain Mauritian Citizenship except through descent (or marriage to a citizen).
All the different methods (retirement for USD 1500 per month, purchasing of property for USD 375 000, employment, investment) only give you Residency - permission to stay long term in the country and unfortunately never Citizenship (a Mauritian passport).
Even after 10 or 20 years of residency, étrangers (expats) in Mauritius need approval by the President’s office to obtain Citizenship, so this hardly ever happens.
If you are looking for a Plan B / second passport, then the following are easier to obtain (read about many of these countries right here on Expat.com):
