One in America where you either work ... or you go on welfare. Would you have preferred welfare? Not everyone has a financial situation that allows someone to stay home.
There are alternatives to daycare centers (which someone up above called "kiddie kennels".)
Husband and wife can work different shifts, so that one parent will always be home with the children. Having a sitter come to the house is also a good alternative. The children can be in their own surroundings, nap in their own beds, play with their own toys, and not be subjected to every virus and bacteria that comes down the pike.
Daycare centers are like warehouses. The owners don't care how precious your possessions are, as long as they are collecting their fees.
