Most of the lyrics are benign and he has plenty of musical talent. But the lyrics that comment on politics are just incredibly brain dead, I don't know what else to tell you. It is proposing welfare recipients as the reason for poverty, but what percentage of tax returns go to welfare? Obviously like, nothing. Additionally his own region of the country has some of the highest rates of welfare recipiency and if that was cut off does he really think that would improve anything?

I think the reason it leaves so many people with a bad taste in their mouths is because clearly a bait and switch is being performed. The first part draws your attention to the issues the singer is experiencing in his life such as low pay, then in the middle he goes on to talk about the "Rich men North of Richmond-" which if that is in reference to DC politicians then fair enough- in addition to welfare recipients as if those two things are related. He is just running defence for the wealthy by trying to distract people from the problems downstream from general extreme wealth inequality by trying to convince us fat people buying candy is causing everyone's problems. Not to mention the humour there is in seeing someone that looks pretty severely overweight themselves calling out other fat people (much like how he is an apparent working class man going after over working class people.)

In my opinion the purpose of the song is just to turn poor people against each other so we won't get any ideas about taxing the rich or anything like that. This is probably be reason why lovely people like Matt Walsh were early promoters of the song.
