There's a difference between NEEDING to work to pay the bills etc etc and wanting more money for a nicer lifestyle, holidays, big house, anything the kids want, nice car, clothes, that sort of thing. That is a choice! No amount of playstations or the latest gadgets can replace a parent being there for their kids.
My boss and her husband are lifestyle driven , like to keep up with the Jonses,and they over compensate with gifts for the kids. I find it all quite sad. I bet they would rather have an afternoon with Mum and Dad and more cuddles than any amount of rubbish they buy them to ease their conscience!
