Same can be said of any type of 'passive' income. In general, I take passive to imply you get out more than you put in. It's the ratio of time invested to time physically working.

Hmm then everybody who is able to set aside some money, has a passive income. How lucky i am!

Yes, that is why it's called "passive investing", because it creates a "passive income".
