I think it is a rather different point. High income employees still earn wages so they would be included in the stats Chuck posted.
Furthermore, treating all high income worker remuneration as return to capital is moot at best. It all depends on the source of income not the amount. A blue collar worker who is making a few thousand $ per year by buying and selling stuff on ebay is more of a "capitalist" than, say, an airline pilot or a physician whose earnings from work may reach six digits.
The point you are making may apply, at least in theory, to corporate CEO or a celebrity inasmuch as his/her income can be divided into rent (i.e. income derived from selling his/her name and position) and remuneration for value he/she creates for the company. In practice, however, that distinction is difficult to make, especially in case of CEOs.
