Another dispute concerns the notion of "overpopulation".[18] In Marx's own time, Thomas Robert Malthus raised dire predictions that population growth enabled by capitalist wealth would exceed the food supply required to sustain that population. As noted, for Marx "overpopulation" was really more an ideologically loaded term or social construct and Marxists have argued there is no real problem here as enough food can be produced for all; if there is a problem, it lies in the way that food is produced and distributed.
