I would add compare it with energy-related industries private or public. Each of Shell, Exxon, Sinopec and China national petroleum earn 3 times as much as Apple. 6/10 biggest companies by income are in oil/gas, and privately owned companies are a fraction of the industry size...

I wouldn't say private since these are corporations usually based on shares systems. This is different from a company such as Valve, for example, which is purely private and where the revenue information is not publicly available.

Apart from this detail, your point is very interesting. I wonder, all industries considered, how much % of worldwide's revenue is earned by nationally owned companies versus the corporations counterparts.

Thanks for the correction, my wording was a bad translation from my native language.
