And thats really what it comes down to and the reason people don't like them or won't play them. First of all they are dead ends, and there is no solution because there's no right ansswer. On top of that... half the time when you play those, there's too many people trying to shovel their own **** on you when you know damn well its not like that.
Examples:
Laborers are often just as greedy as the corporations they claim to fight against (Think labor unions helping to put car companies out of business when they can't compete with overseas companies, thus cutting their own throats over the same greed and losing everything).
Non-religious atheists are often the same zealots as those they hate the most. (communist/socialist revolutions in various parts of the world stamping out various religions with the same ruthlessness as the inquisitions of the middle ages)
Environmentalists out "saving the planet" often carelessly disregard and kill off entire rural communities and their living and hurt the common guy with their own zealousness and disregard. At the very least when corporations come in and put small business owners out, they provide an alternative means to earn a living.
Many times you will find more outright hate filled racism in minority communities than you will in the majority communities that they claim to be oppressed by.
Visit the poor communities, or better yet the Rez and you will see a lot of people with all kinds of opportunities to stand on their own two feet and pull themselves out, but instead, they'd rather drink themselves to death or get so high they kill themselves and blame everyone else for it. And even some of those that make it out and make their way, end up right back there sooner or later. They are locked in a cycle of poverty, but just as often it is their own doing, not because they don't have a way out.
Curiously... these seem to be the least explored directions... in any storyline. Why is that?
I suspect mostly don't want to see that they aren't really the "good guys" they think they are nor do they represent the "common person" the way they think they do. They're often just more of the same thing they are pointing fingers at.... just a different flavor.
Either way, the real answer is that there isn't any solution to those things, and never really was. Because no one can truly save you from yourself except you.
The only thing people can really do is provide the path or the alternative and encourage it... no one can walk that but you.
