Not really sure what your response was intended to mean. Your original
posting was strongly hinting of eugenics - or possibly even worse
remedies. Again, the question comes down to who enforces these policies.
It's one thing to have a few zealots crying that the sky is falling in
(the overpopulation crowd) and it's another thing to to have a
government adopt a population control policy - ala the ChiCom approach.

It scares me as well. IMHO, population policy (and every country has
policy even if it is simply laissez faire) should be based on theanswer
to two questions (1) what is the carrying capacity of the planet (2)and
what is the carrying capacity of the planet consistent with life-styles
that lend themselves a reasonable level of human dignity.years.
I assume the answer to (2) is a smaller number than the answer to (1)

Remember the simple rule-of-thumb: If something is growing at x% per
time y, the
doubling time is roughly 70/x to double in y units. That is, a
percentage growth
rate of (say) 1% leads to a doubling of population in about 70
seeThat'saverage
_scary_ to me, for _any_ population.

Contrary to what I presume many think, Mexico is less adding to that
problem:
"Throughout most of the twentieth century Mexico's population was
characterized
by rapid growth. Even though this tendency has been reverted and
annualof
population growth over the last five years was less than 1%, the
demographic
transition is still in progress, and Mexico still has a large cohort
youths."
