The wealthy may benefit from the existence of low-skilled labour, but compared to what? Do they benefit more than they would from the existence of high-skilled labour?
Yes, they benefit from low skilled labour as compared to no labour at all, but high skilled labour, being more productive, is an even greater benefit. If it weren’t, it couldn’t demand a higher wage.
