I hate it when people don't post because the autovoters are down. In fact I hate precisely the things you have outlined above when people rage about others earnings and lament on the hours they have spent working on something and they don't get paid what they feel they should for it. Expectation is a terrible thing
Expectation and entitlement are two of the worst traits that get exhibited on Steem. I think it is not just here but in the real world, I deal almost exclusively with experienced professionals in business/tech/manufacturing so it is a narrow view of some aspects.
It is a wider phenomenon right enough. I see it must commit in my work where people who do diddly squat complain they don't get promotions or bonuses and you keep thinking, you gotta put some work in!
I do see this amongst the newly graduated and the close to retirement groups. Time in without activity doesn't get access, nor does a fancy degree if there is no effort and proactivity.
