Actually we are hurting for more humans depending on what you want. For example social programs are built with very generous population growth predictions. Social security is solvent to 2035 according to our own government estimates:
> Currently, the Social Security Board of Trustees projects program cost to rise by 2035 so that taxes will be enough to pay for only 75 percent of scheduled benefits. This increase in cost results from population aging, not because we are living longer, but because birth rates dropped from three to two children per woman.[1]
At the rate our population is declining we as a country and society will need to rethink such basic social programs such as Medicare and social security.
