unless you are in a 'profession" or at least reasonably high up in the corporate world, i agree, i dont know how peoples can afford to have a couple of kids in child care, and work as well.
Me, i work full time, take home about between $600 to $650. I could continue to do that with 1 child in child care, but, i think that if i had 2 in childcare, perhaps not really worth it.
Even taking into account the hours that i do, i have little time to keep up with the jobs around the house, be worse with kids - more stuff to do.
And lots cheaper to make yourself a quick sandwich and peice of fruit for lunch at home, then to buy lunch, and a coffee.
