Wealth creation is not value creation.
Just because you put money in your account, does not mean you 'grew the pie' - in fact - you can generate a lot of wealth individually, while shrinking the overall pie.
For example, some kinds of resource extraction do more environmental damage than the profits generated.
'Good Capitalism' creates a ton of value for society, and then captures some of those surpluses.
'Negative Capitalism' just grabs surpluses by whatever means: leverage, legalities, etc..
The problem is we generally don't have a language for distinguishing between the two.
As of today, I believe everything related to blockchain is 'bad capitalism' - in that, the externalities and effort are not worth the benefits (though that could change).
My mother was complaining yesterday about the volume of ads on Facebook - while I think ads are ok, when people are locked in and deluged, its starts to corrode the net value of a situation.
'The Web' and 'Google' probably create a lot of value.
'Facebook' and 'Blockchain' ... more dubious.
Because of the ridiculous amount of money available to be made in net-zero games, even respectable VC's have to pay attention.
It definitely bothers me that there is no language of distinction in the SV.
Finally, yes, greed is a quixotic motivator, and sometimes it actually does help.
