Should I quit my job I hate?

I’ve been at my job for 4 years now, l and I’ve completely outgrown it. The reason I’ve been here a while is because I got a free graduate degree. My reasons for quitting is because we haven’t had a pay increase in 3 years, I’m really bored, and my boss is an idiot and is clueless.

Often he tells people the wrong procedures or forgets it which affects my work, he tells me one thing and months later tell me something different, he treats me like an assistant like making a copy for a paper which is super simple, etc.

One case, we have a new president coming and they need an email for him. I have no paperwork and no details so I tell them I can try to work with IT and worry about paperwork to complete everything else.
He then emails me “He’s an exception, we need the email set up regardless of paperwork!”
What did I just say? He does stuff like this allllll the time! IT ended up contacting me saying they’re asking is o build a roof without a basement and it has many challenges. This could all be avoided if the president would just complete the form I sent which takes two minutes!!

The incompetence here frustrates me so much. I want to quit so badly but I have no job lined up and there is few opportunity right now during this pandemic. I have a large savings for emergencies but who knows when I will find a better job.
