Sounds like confirmation bias to be honest - you have a theory/perception, so anything you hear or see that supports that theory gets noted, filed away, even if you're not aware of it. We tend to discount things that don't fit with our existing world view unless something really pushes us to reconsider so the same kind of little comments and nuances that give you examples to the contrary of your opinion would just go unnoticed day to day.
The next thing we tend to do is make exceptions, so there's every chance that with replies on this thread you're reading them and thinking 'ah well that might be true for you ' because your brain is doing that first step of remapping something. Looking at a different perspective as an exception to an established rule.
Only once we've had our original perception challenged several times or from several different perspectives do we actually start to consider changing or rebalancing it. How's it going so far?
From my own point of view, no. DH is the stay at home parent, I'm the sole earner. I love him, I love DS, but I'd never have wanted to give up my career. He's generous (volunteers, offers his time and support to others, bends over backwards to accommodate my needs and schedule), intelligent, and always has a goal in sight - they're just not about income.
