see you're only thinking about war techs

if you don't go to war, thus, don't need to work on your SDI, you'll keep growing which will inflate the demand for netting techs (bus, res, agri and mil) and since you'll need more units of tech as you get bigger to maintain max tech levels, there will be a net increase in the amount of money generated through tech sales as well as an overall increase in aggregate demand for tech.

When the wars start is when the tech market falls out, which you think would be counter-intuitive, based on your statements.
