The Canadians thought of that too! They give parents a refundable tax credit of $5481-6496/year per kid under 18, and that's just at the federal level.

Plus, basic groceries (like milk, bread, vegetables) and feminine hygiene products have 0% sales tax:

Win, win!
Clearly it's not as smart, exceptional, or functional from a family perspective.
I do hate when people use others as pawns in their arguments though. Are you a single mother unable to afford milk? Inevitably when it comes to talking about economics, the poor/single mothers/etc are always trotted out on stage as reason we need to cut taxes/change the way we do business.
However, I took would like to open the market to cheese. Let the consumer tolerate if they want to buy 'bad' cheese or, as advertised by the proponents, the 'better' Canadian cheese. Let the consumer choose.
In this case, they're arguing from _someone else's_ pocketbook. And it's not the dairy farmers pocketbook or average citizens exposed to global markets pocketbook.
