No, it just wasn't done right last time. The current lot of course have a plan that will work, unlike the previous hundred of attempts. Communism is a good example.
I guess “results” is a different concept from “outcomes”.
One of the noticeable differences in policy considerations and behaviors between the two groups is how they treat disparity of outcome.
Conservatives don’t see any problem with disparities of outcome when everyone “playing” abides by the rules agreed on, or at least known, at the start.
Liberals hate the idea of fixed rules, because they view themselves as intellectually and morally capable enough to dictate “fair” outcomes, rules be damned.
