Of course it wasn't just under the Tories - never said it was. It happened under Labour as well (who in theory at least are dedicated to balancing wealth discrepancy). The common denominator, though, is that it has happened in the EU's watch. Whether the powers that be in Brussels wanted it to happen doesn't matter; it did happen.
Tell that to the Greeks! They haven't succeeded anywhere else, for that matter.
I wonder who you will blame if we leave the EU? A lot of people are going to look very silly.
