As an employer I’ve found the main benefit of having employees with a degree is the degree itself. It proves that person was able to set a goal and hold their stuff together long enough to reach that goal.
People with degrees aren’t any smarter then people without degrees. Although in many cases their writing/communication skills are much better and if they have a technical degree they are more capable of the logical thinking required in many fields.
It depends on the person though just like everything else.
That’s my take as a hiring manager.
If you can’t invest in yourself why should I?
