WHY YOU SHOULD BE A SOCIALIST...
The total economy back in, say, 1750 was about $135 billion. It was $4 trillion by the time you get to 1950. It’s $40 trillion by the time you get to 2000. It’s now $56 trillion. If it doubles in the next ten years, we’re talking about $100 trillion. And by 2030, you’re going to have to find three trillion [...] profitable opportunities for capital to operate at that point.
Now, there are limits [...] and I think we’re hitting those limits environmentally, socially, politically. And I think it’s time we started really thinking about an alternative. In other words, we have to think about a zero-growth economy
And that means [...] it has to be non-capitalist, because that means there’s not going to be any profit around for anybody to have. In effect, you’re going to have to have a nonprofit economy.
