Proletariat ...
... a new definition

Today, we can no longer talk in terms of social classes. At least, the system has become porous, and that’s very well. Knowledge has never been so cheap and accessible. With a bit of will power and sweat, the son of a brick layer can become CEO.

So, for me, the definition of the word “proletariat” has changed.
It doesn’t matter if you’re rich or poor: being a prolet is a state of mind.
You can meet modest people, respectful, endowed with a great generosity of heart and a noble demeanour when facing adversity. And you have well off people who think highly of themselves, but have no dignity whatsoever.
