Then buy shares. Problem solved.
I mean, this guy makes it sound as if holding shares was some trait that gets inherited at birth or something. It's (usually) not. Shares are bought, and since the area of massive unemployment he's talking about is not yet here, people currently mostly do have jobs thus money, so they could buy shares.
The corporate elite are gifted millions in shares/options. It's pretty difficult for someone making 30K a year to compete with that.
The author whines about wealth going to shareholders. To me that just means that people should acquire shares.
But of course, feel free to disagree and keep singing. When winter comes I'll watch you dance.
This doesn't completely solve the problem of wealth accumulation. I think inflation, inheritance tax and regulation against monopolies are still needed instruments.
