You can't really compare the output of a tech company with that of a country. For instance, according to your example:

      Microsoft, Apple and Google combined employ around 148    
      thousand people and have $112.71 billion revenue.
 

That boils down to about 750k per employee, much, much higher than the GDP per capita of any country in the world. Even the US, with a labour force of 155 Million and a GDP of 14.441 Trillion, or about 93k per worker (or 44k per capita), still about 8x (17x) less than the MAG trio.
