I think the title is kinda self explanatory: marketing is the worst thing ever invented by man.
We know that weapons, bombs and so on are terrible; we know that those destroy lives, family and cities. Therefore we hope that those are use as least as possible.
On the contrary, marketing is accepted and promoted, without thinking about the social and environmental impact it has on our lives and planet.
We're all constantly surrounded by messages that are telling us we're not good enough, without that product or that experience. That we need this or that.
A hole of emptyness is dig in our heads and stomaches, with the only purpose of filling it with a product.
Companies are no friends, no matter what their branding project is saying. No company cares for you, they care of their own business, their investors, in one word: money.
And if you feel that this is just common sense, that I discovered that the sky is blue, look around. Look at the people, listen to them. What they did in their weekends, which priorities they have.
It can be quite sad, yes.
