What we are "defending", as per the origination of the thread, is the boogieman referred to as the "modern welfare state", (aka liberalism <--> socialism), specifically the unsustainability of either, as a functional governmental system. Sure it could, but at the very expense of what this country holds to dearly, freedom. Be it economic freedom, religious freedom, or political freedom. And no, that doesn't equate that we, or the European countries are functioning like Stalinist Russia or Fascist Germany, only that those practices and policies that Europe is trying to model is demonstrating its financial unsustainability. And no amount of "taxing the rich" is going to fix it.
It's also why the Swiss electorate debunks you're notion that the most conservative of them run left of our DC Democrats, by voting down the very same efforts, the left is trying to push here. So you can keep the 4wks of vacation a year, and I'll go with the more economic & political freedom here
