AFAIU, neither wages nor investments count as profits - those are paid to owners / shareholders. As far as returning the earnings to workers and local economy via taxes - yes there are expenses, you can't take 100% of income as profits, but there is a lot of leeway to direct the funds pretty much wherever the company chooses. Corporate headquarters in tax friendly countries are popular for a reason.
