Posts outside of this forum, and even here, are full of comments talking about early adopter unfairness...
In general, too many people are jealous of what other people have that they don't have themselves. This is an indication of being a 'small' person. Typically the same persons would look at some rich dude depicted in a magazine and think he's repulsive. His crime: Being rich.
I think it's part of human nature, most of us want everything, but we don't want to do much for it. Those taking the risk of investing early on, or using the system in the very beginning was visionaries, or risk-takers or high stake gamblers. The definition is for you to decide.
The point is that wherever and whenever somebody has gained something that's outside that of the norm, someone somehow is bound to complain.
The same people complaining about early adopter unfariness would've not complained if they were an early adopter themselves (then they would be happy...), and if somebody had told them: Invest now, and reap the benefits later, they would've probably not've invested anyway. What - internet play money ? Ponzi - pyramid scheme - hell no!
Full disclosure: Not an early adaptor, and not jealous of anyone with a lot of money.

There does exist a form of jealousy which doesn't result in thinking the person you're jealous of is somehow in the wrong.
Am I jealous of those who get in on bitcoin way at the beginning? Yes, you bet I am
Do I think they're in the wrong? No, they deserve everything they got and have done nothing wrong - I just wish i'd had their foresight.
