I think it is depressing you seem to want to categorize stay at home parents as some sort of sponger. You seem to only value work that is paid. I find that sad. What couples chose to do with their child care arrangements is down to them. I know a woman with a very good job whose husband is a stay at home dad. I don't judge him or feel he is sponging off her. I respect them for their choices.
I think we are all different, clearly single parents and many couples will not have the chocie for one or or both not to work. But if they have a choice it is not a 'moral' issue. It's a choice.
I think it sounds like jealousy really. I may be quite jealous that others have exotic holidays, a nice sofa, two cars in the family, but it is their money and their choice how to spend it! There is a serious issue for women (or men) who give up a career to be the main carer at home. They do need to have protection, I'd never want to do that kind of thing if I wasn't married to the man.
I've only known one couple in real life where the couple actually shared child care 50/50. I know a lot of people, one family only did 50/50! I think 50/50 would be ideal. But until job sharing becomes a real option for most people it will not work because most jobs that are part time are low paid, low status, sometimes insecure (as in not necessarily a long term contract) and sometimes demotivating! So two people doing that kind of a job each would possibly not earn enough to fund the family.
Two people sharing equally similar job shares (not necessarily in the same company, obviously) meaning both have 50% earning capacity of a full-time job could really work and give both equal time with kids.
But society will need to move in a different direction to the one it is currently going in for that to be a reality, IMHO.
