Surely you do not mean that Keynes or "Keynesians" ignored considerations of profitability? Does it bother you that Keynes in the GT dealt with a time horizon where the macroeconomic contribution of investment to demand was important than the contribution to supply? This seems both useful and realistic when it comes to his project. There are plenty of "Keynesian" models that incorporate a longer period so that both effects manifest. Cheers, Alan Isaac
