You dont really understand how Shares work, do you? Companies dont profit from shares. In fact, apart from when they are actually releasing the shares (IPO, or straight up share sale), then they have no actual direct "contact" to the shares in the company. If Shares go up or down, that doesnt actually impact the company. It affects the shareholders (Investors) in the company, and they might let the Board hear a thing or two if the Shares go down, but the company itself is relatively unaffected (things like borrowing might be affected, but not that much usually).
Shorting can only be done by investors. Yes some Exec's and board members might get shares, but any body in those sorts of positions is legally prevented from trading in their shares based on information that might affect the share prices. This is very strongly regulated, and not something that anyone (apart from the terminally greedy) mess with.
As such, your assertion above is complete bollocks. Well, apart from the part about them not paying taxes. That's a given...
