Complete your studies?

Hello everyone. I once asked this question in an IT sub. I'm really looking forward to your answers and thank you very much for that. About me: 34 Married, child coming to World Tech Lead in a DevOps team in September 85k salary. (90, should I give up my company car) The main reason for studying is money. In other words, more salary at the back. But I'm currently questioning whether the degree will help me at all in terms of salary. Studying is not that easy for me
