you'll pardon me if some economist or technologist has already thunk or disproved this. Â i'm famous for reinventing the wheel...
here's the thought that just occurred to me:
technology greatly increases the commoditization of goods and services.
thanks to gossen's laws, we know that as commodity consumption rises, marginal utility eventually falls to zero and reaches maximum total utility.
if total utility is zero (or even close to zero) amongst all things, there is no differentiation between similar goods and services.
with no differentiation and the ability to consume goods and services ulitmately limited by time (the one, true finite resource), demand is also finite.
supply-side economics is broken because it relies on temporary increases in total utility when total utility is already maximized.
whew... Â that's about all the economic brain cells i have right now. Â tho, feel free to point out weird missing strawman holes.
