You can watch Euro to see how well it works

Exactly. They don't do it. Unlike other progressive policy proposals (universal health care, liberal paid parental leave, etc.), fare-free transit is almost entirely absent from Europe. Sure, there are isolated examples - mostly a few smaller countries and cities that have implemented it. But for the most part, every significant European transit system has fares - and almost invariably with higher farebox recovery rates (percent of costs covered by fares) than systems in the U.S. There's a very good reason why they do that. It's very hard to run a solid transit system if you cut yourself off from fare revenues.
