In our youth, most of us were open minded dreamers. We too thought we could change the world. Then we woke up. We went to war, we got jobs, we paid taxes. We found out that nothing is free and that's when they weren't even giving it away.
These new left wingers are pandering to a group of young voters who were never told no. They are the generation of "everybody gets a trophy" and "it's the teacher's fault, not yours". They have been taught to believe everything advertised as free is actually free. Eventually they will learn that nothing is free. Someone even pays for the hole you are buried in.
