If '40 years' is fast, then yes, things are changing fast... In the sixties, American built, and bought, american goods. We tood pride in making them and purchasing and using them. Foreign goods were considered (and were) 'crap'. but by the late 70's, the 'new generation' was coming up, more involved in *self*... they bought what they considered to be the *best*, which mainly was *cheap*. Japanese auto companies had learned from American companies and they were first to market with small cars which got good gas mileage (for the time) and they made great inroads... more and more 'americans' (young one anyway) now considered American cars as 'crap' and bought japanese Hondas in record numbers; that 'change' kept changing, as other industries (TVs, electronics, etc) were shut down in the US and moved to other countries.. Japan, Taiwan, Korea, Thailand, mexico, south america, Canada, etc... this has continued to today where we really aer in a world economy, and the US has to *fight* just to keep a small part in the economic battles. American car companies are now making good cars; better than elsewhere in my opinion with better gas mileage, more power, more everything, but the parts come from *everywhere*... even companies from other countries bring in their parts and 'make' (meaning assemble) the cars here.. so they are 'US made'..
I personally believe we cannot remain (or recover?) our position as the premier world economic power without retaining the ability to manufacture. Americans have always led the way in *design* of new products, but to a great extent, those *ideas* came from our manufacturing floors... where the ideas began and germinated. We must regain our manufacturing capability. We don't have to manufacture *everything*, but we must know HOW to manuafacture *anything*.. and the only way to retain that is to do it..
Just my opinion..
