In short: no.
We're on quite a low income by choice. DP runs his own business which is barely profitable, but it makes him happy. I'm currently working part time.
It's all about preferences/priorities. For us...we'd prefer that DP work for himself, I have plenty of time with DD, and we have the flexibility to arrange our time as we want. Sure, lots more money would enable us to do things we'd love too...but at this point, the expensive stuff isn't our priority.
