While I generally agree with the argument and am mindful of what people like Paul Krugman say about the value of increased social spending during this period, I have a feeling this particular sentiment will have trouble gaining traction here in the US. People who are already inclined to support Bernie Sanders will be very much in favor of pushing that agenda. But the political reality is that many of the people who DON'T support Sanders' agenda are exactly the type of working people who are struggling the most, and whom he is presumably trying to speak for. There is considerable debate over whether working people want Sanders to speak for them.
A classic technique in sales is to "overcome objections" but unfortunately a significant share of political dialog these days only really tries to drum up support among those already in agreement with you.
I'm totally for raising taxes right now and tax reform in general, but Clinton era taxes won't address the fiscal issues that the people who don't agree with me will focus on. The real problem is the national debt. Now, there may be a completely reasonable approach to dealing with that problem via progressive tax policy, but importing outrage from Europe is not, in my view, going to help advance that approach or the deep-seeded objections to it that exist in the US. Sorry to say.
It's also important to note, Greece has a recent history, both as a government and a society in general, of having been extraordinarily irresponsible with their fiscal solvency. And whatever may be happening in their current parliamentary debate, their only real option to austerity would be way, WAY more painful to their society than the austerity measures being floated. They're about to get dropped out of the Eurozone. At some point outrage will not be enough.
