[lbo-talk] Dumb QOTD: What kind of labor produces intellectual property?

[Charles Turner]

Could someone point me to an answer to this?

Reading Z's _End Times_, and in his chapter about political economy, he mentions the three classical divisions  of income: labor, capital, land ownership.

So what is a royalty? Is it a rent? Is an intellectual property a kind of capital? What kind of labor produces intellectual property?

Thanks, Charles
