He's blaming these problems on "rich men north of Richmond" aka Washington DC, it's not a stretch to think about the policy implications. And what are the policies he mentions? Taxes being too high and welfare benefits being too generous. Again, not exactly a stretch to see the implied recommendation is tax cuts and welfare state cuts, pretty much the core planks of the Republican Party platform.
I definitely agree listening to the music people make and listen to can be a good way to gain insight. Really my problem with the song is the opposite of what you imply - I don't wish he had policies drawn up at all, it's the extent to which he does reveal policy preferences here that I have a problem with. Not that this guy is necessarily a piece of shit or anything, it's just that what's being revealed about him through this music is the undercurrent of conservative ideology that is the water in which he swims and which he's unconsciously reproducing in this song.
