'Money, pay, belief and acceptance' listener question

I am in part aiming to transition from a career in the corporate world to a career in the third sector after voluntary work in the sector. I find myself naturally moving in that direction and really energised. One question I have been contemplating is the significant disparity in pay between the two sectors. I can see that money is a concept and as such nothing about it is ‘true’ and yet it doesn’t seem to make sense that they should be so differently paid. I appreciate that there are narratives/ beliefs around the third sector being short of money and people working in the sector get paid in fulfilment and yet I feel by accepting these and the salary that comes with them I am seeing the beliefs as true and being constrained by them. I can see at times a sense of ego popping up feeling it deserves more money and is ashamed it will not get this but when this isn’t so strong I can see that there is information in this which may be helpful. Would love to hear your thoughts on this.
