Dude, you are overthinking this. Like, you spent longer thinking about the alleged pacification of masses by agenda driven producers than said producers spent thinking about the songs in question.
There is no agenda and/or purpose behind this. You just made the mistake to assume your views on one of the most subjective topics possible (music) are fitting for music in general. That's not the case.
You might like a little rebellion, commentary, what have you in your music. You might like to express the issues that move you via music. Many others don't.
The charts are, what people are actually listening to, so don't mistake the charts for something that's only pushed by labels or something. It takes listeners and labels to push something into the charts.
That doesn't say that there are never songs of the critical variety in the charts or anything. It's just rarer.
