That wouldn't support my claim very much at all, really, because there are too many confounding variables and too few countries to support any kind of causitive claim. I don't know if countries with subsidized childcare have more antisocial behavior, and I don't think it would shed any light on the situation. The subsidization is only relevant insofar as it increases utilization of childcare.
The only thing that can shed light on the question of whether childcare is harmful to children is scientific research with large sample sizes that carefully control for confounding variables.
