Here's my opinion.
Every morning you drive on a road you didn't build, drop your kids at a school you didn't found, and trust that if your house catches fire, someone will show up without asking for a credit card first. None of that came from a business looking to profit. It came from all of us chipping in so everyone gets something we couldn't manage alone.
That's the basic idea behind socialism: we're stronger when we pool what we have. And we already live it. When big banks and automakers were about to collapse, the government stepped in with public money to save them. If it's fine to share the risk for corporations, why is it "radical" to share it for regular people?
So the question isn't whether we do socialism. We already do. It's who the leadership is willing to do it for.
