I think the basic difference to the underclass and the working class is in the name, the working class will work, no matter what, as they have a strong work ethic and would rather earn a few pounds than get it in benefits
and before anyone starts screaming at me, I'll try to explain myself
we have been on very little money since ds was born, 10 yrs ago. dh worked shifts for the first 7 yrs and I had to work around his shifts, we have no family help so free childcare is just a dream here. so I childminded, worked in an ironing shop, cleaned pubs, basically did anything that would let me work flexibly and whenever dh came home I went out to work.
at the time we also got working families tax credit, as we had less than £15k, ever with both working. but any earnings of mine brought down the amount of tax credits we earned, so I sometimes worked for around £3 and hour, taking the loss of tax credits into account.
I've been working now since ds was 9 weeks old, I've tried everything, babysitting,cleaning,home help,pub work,everything I do I declare as earnings and so lose £'s in tax credits. now I work in a pub doing odd shifts and getting minimum wage. my neighbour hasn't worked for 8 years, lives with her partner (who workd casual cash in hand for a few months a year)and claims every benefit known to man. she told me she has her rent and her council tax
paid. she also told me she can't afford to work and see's no reason to get out of bed for a pittance and then laughed at me when I told her what I do. she thinks she has one over people like me, the working poor.
THAT is the difference between the underclass and the WORKING class.
