Sounds like the same tactic being used in the US. They've found a catch-phrase they can use to get the poor and downtrodden to stand up for the people who are stomping all over them. Start throwing around words like "class war" and you're THAT close to "communism" which will get even the most shit-upon citizens all riled up.
Its funny that holding down the minimum wage or an increasing pooling of wealth to the top isnt class warfare, but removing the stupid private health care rebate is...
The problem is, everyone thinks theyre middle class, even the rich and poor... Its why people who earn over 150k can say with a straight face that theyre not well off.
