Interesting and very true! If you don't mind me touching on one thing you mentioned though that I think might actually in reality be the complete opposite:
'All products and services are marketed to make you happy with what you are receiving. '
I think that most marketing is aimed at making you feel UNhappy, UNworthy or UNsatisfied. Then the product is presented as being the solution! So, yes, the product or service is supposed to make you happy, but what we are told on a subconscious and sometimes even plain conscious level is quite different. You didn't even know that you were a failure for one thing or another but now you do, you want to have this product to no longer be a failure and to be cool, young, respected or whatever this product promises you.
It creates issues that weren't even there before, but now they are and you'll happily pay to improve.
Yes this is true. We are marketed to bring out our insecurities and then buy the products or services that makes us feel good again. Great add @tishyaoedit! Thank you
