Okay so you're tying career(in this case farmer/full time mother) to self esteem. I can see it tied more directly to self worth and then to self esteem, the two usually go hand in hand. I don't see how it's different now. Most people still work but I don't think they revolve their self worth around their career or jobs as much anymore but many still do.
I get the religion thing, you need a reason/explanation for your purpose in life.
