If you adjust for countries with small population and/or small area (basically city-states with economically insignificant countryside), then then GDP (PPP) per capita list would look like this (Wikipedia):
Norway - $54,947
United States - $53,101
Switzerland - $46,430
Canada - $43,472
Australia - $43,073
PPP (purchasing power parity) means that the GDP per capita is adjusted for prices. The nominal GDP per capita would look a bit different. USA looks really really good on this list, especially when you consider that it's with a huge margin the largest developed country in the world. Although USA has quite high nominal GDP, it is also quite cheap compared to other countries on similar level (Norway and Switzerland are both super expensive).
