The show "Happyish" is one of my favorites right now...the woman hates all the blatant advertising bullshit, the husband WORKS in advertising and hates it...but life (in the last episode) just sort of ground them down and they caved and bought the new 'must have' phone and crap for their kid.
Advertising, at its core, is manipulation. Maybe it started out as just a form of notice that someone had something for sale: "Grog have dead mammoth, trade half for wife, or dry cave."
But now it's evolved into mind fucking spiders that try and get you to reevaluate your very existence and being: "You deserve it." "Life is short..." etc.
Visit any car lot for great examples. Read any car ads: "it's sexy" "feel the power" "let's go places" etc.
The alternative is to actually think for ourselves, and choose things that enhance our lives instead of encumber them.
Easier said than done, even for MMM converts.
