I think this is another problem with how our society has evolved over the last 20 years, everything now needs some kind of qualification which means less and less jobs available to unskilled workers.
When I was a teenager, babysitting was something most of my [female mostly] friends did for an extra bit of pocket money, it was an unskilled job. Now though, to look after kids even for a few hours you need several NVQs, a CRB check and some bull**** certification.
You could kill unemployment over night if all unemployed people could act as child minders and look after the kids of those with long working hours but because of the above that isn't possible and the whole thing has been turned into an 'industry'.
So when you have kids are you going to:
a) Let them be looked after by Shazza who will be giving her dope selling boyfriend favours, or
b) Let them be looked after by a professional who cooks healthy meals for them and provides a structured framework, timely and precise feedback, appropriate stimulation, advice and support, recognition of potential areas of developmental delay, proof of their safety, oh jesus do I really need to go on.
