I feel like he defined the term quite a bit before he used it. It does describe very specific way of earning income.

If it's a very specific way of earning income, isn't the income, thus, earned?

That depends on what the definition of "earned" is: "obtained" or "gained deservedly". I think this is an example of the former definition.
