You suppose the idiots never heard of “backhaul”? Do they think all trucks and ships run 100% full all the time? Are the hundreds of container ships arriving from China all full of goods when they return from West Coast ports to China?
This is a perfect illustration why leftists cannot understand capitalism or be capitalists.
I say forced indoctrination of economics, problem is that they are of such low intelligence that they would not understand course work.
Wasted time and effort.
