James, 
I don't think we are going to agree. First, I said that capital goods 
are a stock not savings. Secondly, I just reported what Solow and others 
who have done serious work in growth theory have concluded. If you think 
Solow is wrong (and I'm no Solow fan) then refer your arguments to his 
work.  
In regard to Keynes and consumption and investment. Keynes's discussion 
of "The Propensity to Consume," Book Three is only 43 pages.  
"The Inducement to Invest," is 114 pages.  And Keynes actually says, 
"employment directly employed in investment as the primary employment" 
GT, p. 113. The consumption expenditure was simply a derived and passive. 
Investment, on the other hand, was quite dynamic. Keynes, in my opinion, 
was really a monetary economist. 
Have to go....
