Do we ‘want’ or do we ‘need’ what have become known as “labour saving” technologies…?

Surely one of the most destructive and corrosive phrases ever coined by industry is “labour-saving”?
Not only does it imply that human physical exertion is something that should be avoided, “I’ll take the car”, “…the elevator”, “the escalator”, but sadly some individuals have, over time, adopted a mindset that they’re actually above exerting themselves, that they’ve perhaps achieved such an elevated status in life that physical exertion is somehow below them?
Whilst the car, the elevator and the escalator are all amazing inventions, they are now being used through want as opposed to through need. Somewhat paradoxically, as human athletic performance gets ‘evolved-out’ over time due to laziness, these devices will eventually need to be used rather than being used through choice.

There are now more obese than skinny people…
