Atheism and issues with God

I still fail to understand to this day, why people believe God is good, loving and giving. The fact is most people in this world go to bed hungry every night. 80% of the world's population lives with less that $10 a day. 25'000 children die everyday due to poverty. Natural disasters such as the recent earthquake in Haïti, a country so poor that even under normal conditions people have a lot of trouble roofing and feeding themselves. Yet I hear that God is good? Explain to me how this man who sits supposedly high above us, is wise and all knowing can allow such injustice to happen in the world. Avoiding the question that he gives us the freedom to make our choices that guide us through life, how in the world can he just sit there? Because I must say, God must be really good, particularly when you have a roof above your head, a comfortable indoor temperature, hot water, a plate full of food in front of you any time you're hungry, and a family in good health. Then I would agree at that point you must feel blessed and thankful to the all mighty God. Yet, how is that usually poor people are the most pious ones? The ones the church goes after to draft into heavy faith? These same people that the Catholic Church tells not to use contraception... And why may that be? hum maybe to keep them poorer with an overwhelming amount of children to feed so that they continue blindly following faith.
"El mundo esta mal hecho" is what my dad loves to say. Meaning the world is badly made. Well it really is, a few of us are fortunate enough to live in relative comfort, while the rest live in miserable conditions. So who is this mighty powerful and good God that makes a world so unfair yet who receives praise everytime something good happens to a pious person? I don't understand it, how about we thank him for all the bad things that happen to us as well. I'm pretty sure that in that Pros and Con lists taking every citizen in the world, you find many more Cons than Pros.
Now I'm an atheist, I'm pretty convinced God doesn't exist, but I can't rule out the possibility or that would be being close minded. On the other hand, assuming he does exist, I think he is a lazy underachiever who is praised excessively for his doings.
