The motivation behind it is to buy as many votes as possible, if anyone who actually needs help manages to get some, that is a coincidence.

If you are going use the Single Mother as your benchmark, you need to ensure they are the ones who get the service, not, as currently, the ones least likely to get the service. 

ALL my professional friends have kids in subsidized Daycare, often picked up afterwards by the Nanny. 

My friends who run daycares all say it's the same pattern. 

Single mothers work antisocial hours, when daycare isn't available.

My old Government office has a very nice purpose build daycare facility; It was nice to see the kids being picked up by their dual income parents, all of whom rushed off at 4.30 to go collect the kids.

The single mothers who cleaned the offices at 6:30pm didn't have access unfortunately.
