You realize humor isn't always the point, right? Relatability is one of the biggest reasons people read comics like Garfield. It's not funny that he hates Mondays, it's relatable. It's human to seek that kind of connection. People often enjoy reading Garfield comics because we enjoy finding validation of our desire to be lazy. That being said, they can also be hilarious; I remember rereading this one all the time as a kid, and just dying of laughter.
I'm not super familiar with this comic's artist, but I can see why you compared them to Garfield - this comic clearly isn't trying to be funny so much as it's trying to connect with the reader about our shared frustrations with the state of the world. It reminds us that, while the world is stacked against us, we still have like-minded people to turn to for support. It's nice to see that.
