+Philip Wright Declining population means declining number of people to pay taxes, but more people retiring and requiring social services. This means fewer people carrying a larger burden.

Less people are required to produce more. 

Its hard on the people required to do the producing.

I agree, relying on infinite growth to fund programs will eventually fail. (Preaching to the Choir)

I disagree that there is plenty of production for everyone. The "'missing trillion" of dollars will not produce food and fuel for people, only effort can do that. That effort requires working age people.
