I'm curious about this profession; what does day trading provide to society?
Nothing, Day traders exist for their own greed, nothing more.
They waste oxygen.
Anyone who bought a bunch at $1200 and than sold it off at $700 in a panic is NOT a day trader, they would be a clueless noob..
So, The vast majority of the human population?
Based off my experiences with people in general, The vast majority are self-centered, poorly educated, and weak(spiritually, emotionally, and physically).
I like your style, sir.
