More or less
As the Copenhagen conference heats up, a new proposal has been brought to the table: a planet-wide limit on the number of children people can have. The rather straightforward rationale, as explained by both a Chinese official and a Canadian journalist, is that smaller human population could significantly reduce greenhouse emissions. Needless to say, this has sparked considerable controversy.
In our work on socio-economic intutions, we have discovered that liberals and conservatives have a very different understanding of the role that rising population plays in wealth creation. Specifically, progressives and liberals are much more likely to endorse a Malthusian view that growing number of humans decreases mankind’s wealth, while conservative and very conservative voters are much more likely to follow a Hayekian conclusion that increasing number of humans leads to greater wealth for all. Here are the results, based on a Zogby Interactive poll of almost 5,000 likely voters.
| Progressive | Liberal | Moderate | Conservative | Very conservative |
Libertarian | Total | |
| The more people there are, the more wealth there is | 17% | 18% | 24% | 51% | 61% | 54% | 37% |
| The more people there are, the less wealth there is |
61% | 61% | 54% | 31% | 23% | 26% | 43% |
| Not sure |
22% | 20% | 21% | 18% | 16% | 20% | 19% |
