It's everywhere nowadays, and I think it needs to be discussed here as well, especially on a communist community as we are. 
While I agree with the sentiment expressed in the song, some lines about fat people on welfare are absolutely baffling. As if they are the problem. What the hell?
But overall, this song speaks to me. I feel communist and workers really do understand the frustration of this song, and can build bridges.
OK, I'll bite. It's got a "wish I could go back to the good old days" message that is immediately suspect because they good old days were only good for certain people. Blaming poor fat people for other people being hungry is just more of the obvious divide-and-conquer that has lead to the absolute destruction of the welfare state, and reminds me that "welfare queens" are black-coded even though loads of white people are on assistance, but they think they deserve it, unlike "those other kinds of people. Then there's complaining about taxes. This whiffs of libertarianism to me, given the overall tenor of the song. In conclusion, in my opinion this song sucks and its analysis sucks. It blames all the wrong people for the very real problems of today.
