One of the biggest factors in the cost of living is where we live. Simply just be moving can we increase our standard of living. Living in New York for instance will cost up to 10 times more than living in Buenos Aires. Living in Michigan will cost far less for the same sized house as New York City. If you work online you have the luxury to become richer just by moving locations.
When I travel for instance I tend to spend more time in cheap places and less time in expensive places. Why? I can live so much better for less in cheaper countries. My hostel room cost $9 a night in Buenos Aires vs $28 in New York City. Not only is the accomodation cheaper, but eating out is also relatively affordable.
