Dems run on social programs, which isn't the same as full on socialism. If what the dems are fighting for is Socialism then Germany is a fully socialist country. Even if Bernie had all of his wishes they'd still be merely catching up with other developed western countries. What Americans call "Socialism", every other developed nation calls "human decency" or "common sense".
I don't know what that has to do with anything though. All democratic candidates want the same thing. And even if some don't agree, the policies that are being pushed need approval from the whole party to get through, so it's not like that a radical Democrat would be able to push all of his radical agendas. That's how democracy works.
I think the best example that I could show you is California. You cant tell me that they are nt trying their best to as you call it"catch up to the EU". Its the worst ranking state in the US and before the insanity they where the best. Now the have the highest wealth inequality. The middle class shrinks every day. Homelessness as far as the eye can see. Rich neighborhoods gated. Thats what to many "social programs" do to an economy. The state has not yet taken the resources of the big corporations like google there cuz they know they will just flee to either another state, or out the country if need be. Radical leftist have full reign in California and nobody stops they crazzy policies they put up and look what they have.
Look, social programs are not a bad thing, dont get me wrong. But you have to realize that good intentions is not all takes to lead a nation. Inequality is a law of nature as all people are inherently different and as such different outcomes will result from it. Sadly because of it, some will end rich some poor. But its impossible to completely fix that gap that nature made. If all needs for the poor where met, like guaranteed housing, health care and food and education, they would not need to even get off the bed in the mourning. The more the needs are met, the less people will work to improve themselves. I say we do have to help the most needed out of some hardships, but never completely remove all hardships from them.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
