Maybe they're poorer in aggregate? I mean, sustenance-level poverty is one
of the prime causal precedents of high fertility, and most dictatorships
are poor ones, because of ineffective rule of law and wide-spread
Sure, there are a few wealthy dictatorships (Saudi Arabia comes to mind),
but that's because of independent factors (which usually do not touch the
>Does population growth influence choice of government?
Under extreme poverty, likely not -- poverty would drive people to take
care of their own business, not politics. Under other conditions, probably
yes -- relative poverty and the greed thereoff is how we got the welfare
state. We would expect the per capita lack of income in young generations
induced by population growth to affect at least redistributive policy. For
example, I wouldn't be surprised if that was the precise description of
how politics in India works right now.
If the latter hypothesis pans out, we have to be real grateful that
industrialisation proceeded so rapidly in the West, unhindered by
full-grown democracy. Otherwise we never would have tunneled onto the
level of wealth which throttles population growth, without bumping into a
democratic political wall with the working class requiring income
transfers -- the latter slows growth, so we could well have become stuck
>2. Should economists try to maximize GDP, or per capita GDP?
Neither, I think. Maximizing GDP would not be conducive to general
welfare. Maximizing per capita GDP today would also violate individual
choice, if we also take into account individuals' time preferences. I
would take full heed of the principle of revealed preference, and just let

I would side with Robert Kaplan
(http://www.theatlantic.com/issues/97dec/democ.htm) and conjecture that
democracy can only survive in a relatively homogeneous population,
constrained by the rule of law. Secondarily I would claim that democracy
can only survive where its transaction costs and the steadily increasing
dead weight it produces can be absorbed by economic growth. Such
conditions seem to sweep most of the unsuccessful democracies from the
They might sweep us under the rug as well. The conjecture might be false,
but at least it supplies some basis for the claim that growth is
"necessary" (which it of course isn't in any purely economic framework).
