If we had sustainable practices, at least of 3rd of the people in the United States and Western Europe would have a standard of living similar to the people in 3rd world country. This is assuming we don't compensate for things by exploiting more vulnerable populations.

...Reddit is the opposite of Republican. The people there are aggressively far left. It is hard to believe that it's not an artificially enforced echo chamber.
The problem with echo chambers is that they are politically sterile. By aggressively forcing Republicans and moderates off the platform, we lose the ability to influence their stances and opinions. It becomes a circle jerk.
