Bob's Burgers breathes class consciousness. There's an episode where the kids are forced to volunteer through school, and the rich landlord makes no secret that he's exploiting their free child labor to clean up his beach. The concept of collective bargaining is played with when the kids decide they don't want to do that work for free. That episode also includes the lesson that the rich will absolutely use you and screw you over to further their own desires.

The rich landlord is frequently shown dicking around as if the people around him are playthings. In another episode, his tenants decide to hold a rent strike. The landlord uses classic divide and conquer strategy to turn the other tenants against Bob, the leader of the strike, via a water balloon contest (it makes sense in context.)

That's not even touching the realistic struggles that Bob, Linda, and their family have to live with day-to-day. Despite characters sometimes being, well, completely wackadoo, it's probably the most relatable animated show I know of.
