Homo Homini lupus

"You can organize societies that espouse, promote, even glorify, one Homo sapiens's boot crushing another Homo sapiens's face for all eternity"

We are not far from that:

"I'm more and more convinced that the markets (I'm really just stressing the stock markets now) are a brilliant way to swindle the masses of their money.

Now consider how much any single stock investment will be worth over the long haul.
Aren't we in the end, just gambling when we 'invest' in the market?
After all, we are betting that we can sell the stock at a higher value than which we bought it. We can be sure, that one day, the stock will be worthless. So effectively, all stocks are ultimately worthless.
So we buy worthless stocks, in hopes of unloading them to another sucker at a higher price?
