I agree with this. I don't think he's a bad dude and I do think he really wants to help me more than almost every other politician, but his policies definitely have socialist flares to them. I supported Warren, who also supported policies with socialist flares.
For example:
"Sanders wants to provide workers with an ownership stake in their businesses: Under his proposal, employees at large companies would be given 20 percent of the shares. They would also have control of 45 percent of the seats on the board of directors at corporations."
Support it or not, this is a brand of socialism. Capitalism makes more of a distinction between the worker and the owner.
I think there's a fuzzy line between fair capitalism and socialism. Ultimately, the labels probably don't matter. I don't think we should eliminate any socialist idea on the face. As pointed out, we already have tons of things that fit the definition of socialism.
Universal Health Care is a good idea, but it has its drawbacks. I am navigating a really complex medical problem. I didn't receive treatment until I built up a rapport with a doctor. There's no way I would have received the same treatment if I was just another number. Sure, my premiums would be gone, but would it be worth it? I think it's fair to at least question this.
