According to popular wisdom, a good father provides for the whole family.
Mormons know and teach their young children that a father's role is first and foremost to provide for his family. I'm not entirely sure what "provide" is supposed to mean, but I'm pretty sure it has to do with money so the family has a roof to sleep under and food to eat (providing everything else the family needs is a mother's job).
The point is that our Heavenly Father loves us so much that he have us another father - an "earthly" one - to do all the stuff that He would do if he were here. He's basically delegated the work for the time being, but don't forget that everything we have comes as a blessing from Him. Anything your earthly father brings home came from God because God made everything (through Jesus).
The human family stands largely in need, but you can't blame God for all the negligent earthly fathers. You just can't. It's not God's fault that those who have do not share. He can't make them share. There's nothing questionable about the way Heavenly Father distributes his blessings.
