Actually some people believe that there is more than enough resources to go around, just because those were all put in place by God for His creation. There's a famous story Jesus tells about the birds and the flowers not worrying for their provision....

I have not seen this quantified, so I don't have an opinion whether it is true or false.

The fact is that currently the number of people living in extreme poverty exceeds the number of those living in excess by orders of magnitude. Some people think this is fair, others think it isn't.
