> In general, I don't agree at all. Rich are "freer" but they definitely don't work fewer hours than poor on average. In USA the Rich became rich mostly by working.

Dont forget about inherited privileges. If work was the primary driver of wealth, we'd see a much more even distribution. I suspect the eager CEOs either want to inflate their contribution (i know plenty who dont) or actually work more because it is their earning and not just salary plus maybe arbitrary bonus.
