The government there also gives incentives for kids though I think if you gave people a 100% break from income tax for 2 years after each kid is born, it would move things along.
I have heard a lot of folks don't pay those taxes anyway. :)
The house/farm is a good incentive, where do they offer that?
I still think an all out ban except in instances of rape or incest would be helpful (if it was enforced well).
There's a real need to push for people to move east too, before the Chinese manage to have more folks in Siberia than Russia does.
