Price will extend the supply indefinitely.

True, but when we serfs can't afford to get to work any more, how do you think that might impact the economy?

I don't know what serfs will do about it. Once upon a time, guys with a high school education could get a good factory job and make a fair living, enough to raise a family, take vacations, replace the family car, have a house and mortgage, etc. All this is undergoing big change.
If you buy Michael Porter's Competitive Strategy/Competitive Advantage books, the "replacement product" concept will extend to transportation; its possible cars like we have now will disappear and something much more economical will take its place.
Someone will come along with a better idea that sells. It always happens.
