If they actually do any labor in those tasks, then yes. Labour doesn't necessarily mean the bottom level stuff. Management still takes work. Setting up new businesses takes work.

Investment and ownership intrinsically aren't really labor though. Just owning the company doesn't add anything of value to anyone, and investing is more like a trade agreement. Should be honored, but not necessarily treated the same. Because investment does help create, and the owners presumably have done work to get from nothing to something of value in the first place. Ideally, anyway. This isn't necessarily true in reality. Plenty of owners inherited, and why should they be entitled just for being born lucky?
