Socialism has failed everywhere it has been tried. The argument for this concept working in America is that it will be the one time it does not fail. This is the lie that Bernie Sanders and Alexandria Ocasio-Cortez and many others will try and convince you of in order to push their agenda forward to changing this country at a fundamental level because they do not like it the way that it currently is.
Socialism has crippled economies and destroyed any notion of quality of life as it makes the wealth gap and the concept of "fair" to be above all else including the well-being of everyone.
Sanders gets a pass from the media on this because he is on the side of the media that wants their slice of control when it comes to the narrative. They will buy into anything that is sold to them as long as they gain a semblance of power through its airwaves. They want to be an arm of any administration that gives them direct contact and influence over the people.
They want to have the job of moral compass and thought and information control and will go to any lengths.
Socialism gives them just that and puts them back at the table like they had with President Obama and so many other administrations that gave them carte blanche.
Sanders may not fit the mold of the party but he does fit the endgame. The ends justify the means and if that means that makes them Bernie and Socialism apologists then they will simply ask where they can sign up.
