Advertising improves…nothing. Absolutely nothing.
To be honest, isolating from ads pretty much improves my (and maybe your) quality of life.
Resist "free" TV supported by ads, use Adblock Plus or uBlock Origin with a supported browser and avoid social media forcing ads on their users - these simple measurements alone will
- make you want less things you cannot afford
- give you more free income for things you need because of 1.)
Both aspects significantly improve your well-being, especially since they can enter you into a positive feedback loop.
I personally blame ads for many social problems (including a good part of property-related crime) in our society.
