That documentary is great.
Think about this for a moment, if we (and we can) make things last ten times longer, like a tire or a battery, or a car that got 75 mpg, think about the negative impact that would have on American workers. Tire companies would lay people off because consumers are not buying tires last they have. More Americans unemployed = bad.
The military has access to some of these durable products so the technology is there, but regular American products are designed to be purchased, used, and purchased again to generate the big $.
