Something to mull over...
This applies to plenty if not most things in life , sales /consumer. If nothing was never changed or reinvented, what would we have today ? Why change the design of a pickup , It already has wheels and can haul stuff. Are 15" wheels/tires any better or worse than an 18" Why not just paint trucks all one color , do we really need 4 shades of blue ?
How about a knife for skinning coyotes ? Does anyone really need a custom blade ,when a factory production will work just fine ?
Why is there 5000 (just picked a number) craft beers ? Miller not good enough ?
This could relate to anything .
Change, inventing ,reinventing , = Jobs= sales= money . $$$ keeps life in forward motion.
