A child brought up with a happy, stable home life, with good access to health care, an excellent education and opportunities to develop their potential, is unlikely to grow up workshy. He or she may possibly end up unemployed if there aren't enough jobs available, or because they can't get adequate childcare, or because they have to care for a partner or relative, but that's not the same as being workshy.
So how do you ensure that all children are brought up with happy, stable home lives, with good access to healthcare, an excellent education and opportunities to develop their potential?
Well, you can deprive those who are least likely to have this of even more money... cos that will help won't it. 
Or, you can invest in things like schools, sure start, social services, CSA, community centres. You can increase education about healthy relationships, parental responsibility, etc. Except all this is being cut too in favour of the option above.
Like many, I believe that failing to look at history and learn its lessons means that you are doomed to repeat the mistakes of the past. We only need to look at our own country's history to see that demonising the poor - even those who 'deserve' it - does nothing to improve the situation (although it can help the mean spirited feel better). Whereas investing in people and providing them with the means to help themselves, does.
