I've been thinking about this in particular, and it seems it's a bit like Reddit.
Reddit isn't bad in and of itself. The creators developed a means for subs to moderate themselves through user input in the form of upvote/downvote karma.
When utilized most reasonably, bad elements can be downvoted and repeated abusive behavior by those elements results in an inability to post at will.
However the system itself can be abused in the form of downvoting otherwise reasonable positions that simply don't fall in line with the sub, until those with contradictory views can't respond to all comers and are effectively smothered by those with the sub's preferred position. Boom...echo chamber.
To clarify, I don't form my political opinions from Reddit if that's what you're insinuating. Doing so is no better than forming them from instagram posts or tweets, as well as corporate MSM like Fox or CNN. Reddit is great for finding political images/cartoons/memes though, for all political views. Most of the images I post in this thread that come from reddit are copied from the subreddit r/LateStageCapitalism. There's some funny/relatable content in there, but to be fair, I disagree with at least half of what gets posted there. There are regulars in that subreddit who think that we should completely abolish the idea of a market economy or private property, and that we should have communism exactly how Marx proposed it, and post memes which support those views. That subreddit has memes for anything as left or "lefter" than democratic socialism/critiquing American capitalism.
And I absolutely agree about it Reddit being an echo-chamber. In many political subreddits, whether it be LateStageCapitalism, The_Donald, or simply r/politics, dissenting views are not merely downvoted, but the users who post these views, even in good faith, are usually permanently banned from that subreddit. Certainly not a way to have healthy discourse nor is it a democratic system.
You basically proved my point about Reddit. Being that the meme was from r/LateStageCapitalism, I had thought it was accurate and didn't even bother to fact check it. And quite honestly, if it was a similar post but had a right-wing undertone to it instead, I would have likely doubted it. I've realized that I haven't been as aware of my bias as I should, I guess.
Whether the image is genuine or not though, the point it makes still stands. At one time in American history, children half my age could work 10+ hours a day in steel mills across the rust belt without receiving any education, safety standards, or adequate pay, all so that powerhouses like Carnegie could reap as much profits as possible. And when politicians finally realize how immoral it was and propose legislation to outlaw it, they faced harsh opposition from these corporate lobbyists. "If child labor is outlawed, how could we afford to stay in business and innovate" basically summed up the argument the lobbyist used. This country can make great strides today if our politicians, on both sides, would not be spineless and actually stood up to lobbyists instead of getting bought by them, and actually serve the constituents that elected them to begin with. We have to remind ourselves that outlandish practices like child labor were not outlawed because the market regulated itself or actually cared about being ethical, but because politicians did the jobs that we elected them to do. But as things get worse and worse and we move closer and closer to a corporatocracy, it honestly doesn't sound unreasonable that a workers' revolution is the only way to achieve real, systemic change, getting money out of politics once and for all.
