Jassy, I don't understand the confusion. Hobbies depend on the family, same as days out. Money being necessary is somewhat gray, as I said to someone else. However, for arguments sake, a single mother earning £20k is going to find her money a lot more necessary than two working parents earning £100k a year, yes? I think this is going to be very hard to talk about without specific examples if you're going to insist on being black and white. For sake of argument, lets say when both parents are 40% tax payers.
Ah, but here's the problem. You said people were selfish for working full time unless it was necessary. When asked what constituted necessary, you said enough for a good standard of living, and when asked what you thought that was made up of, reeled off a list of things like hobbies.
So, now you're saying that 'good standard of living' is entirely subjective depending on what the family had pre-children? It depends on the family what they will find necessary? What about non-material necessities?
This is a problem with the argument you've set up - you consider people selfish for working full time if it's not financially necessary, but your description of what makes it necessary, when challenged, is so woolly you could knit a jumper out of it.
If you're going to call people names, you should at least have a consistent basis for which people you are calling those names.
Not sure what you think of me and my DH. We both work full time but compressed into a 4.5 day week each, with a lot of overtime from home after hours. We need my salary to continue something close to our current standard of living, we could manage (with worries - how much is too much by your measure?) without his. Which one of us is selfish? Both? Him? Neither?
I don't think it's necessarily selfish as there are many reasons why someone might not want to adopt a child, personally I don't think I would be the best person for dealing with the difficulties adopted children often have. That's not selfish surely? Wouldn't it be more selfish to adopt and then realise you can't cope with the child and have to give them up?
Having children full stop carries those risks - it's a selfish gamble that is about fulfilling the parents' desires. No two ways about it, really.
