Isn't that just restating a (probably) truism that investment into financial bubbles tends to be easier than expanding real production? Where does the extra profit go (in the absence of windfall tax)? I doubt it goes to expanding production, because without windfall tax, you won't see demand change (and, btw, with windfall tax you don't have to estimate, you will directly see customers having more money to spend). So it will go into stock buybacks, real estate and other ways to inflate asset bubbles. These are seemingly easier ways to park money than to make actual real investment decision of expanding certain production.
