This is fine for the smart people. Within a couple of generations smart people will be very scarce, very well paid, get excellent health care and probably be cloned (if cloning turns out to be practical).

Whle Malthus may have gotten figures wrong, the basic premise is sound, and has been born out in practice. Every increase in food supply has been met with an increase in population. If you woudl like some interesting figures to look at, look at figures of fosile fuel usage vs population. In effect, our population explosion has used limited energgy stored in the earth to fuel our growth, and will fall with those supplies as well I believe.
In just a quick search for somethign online I found this:
from http://www.holon.se/folke/kurs/logexp/logexp_en.shtml
"The human population has changed very little during 99% of its existence of a million years or so. During this time, the population increased to about 10 millions. Only during the last one percent of its history, the human population has changed dramatically.
During the time from the first settlements to medieval time, the population changed from about 10 millions to around 500 millions. This change occurred in only 10,000 years, or about 1% of the time of our species has existed.
From medieval time to about 1850 there was a stepwise increase of the population.A large change occurred from medieval time to about 1850. In 0.1% of our species existence, the population doubled to about 1 billion.
After 1850, industrialization occurred and fossil fuel usage began. The slope of the curve changed dramatically (even in logarithmic terms). At this break, the human population got the opportunity of using more energy in an activity than it gives back (EROI below 1, The rabbit limit.).
This opportunity is used in nearly all industrial processes, including food production. In about 100 years, 0.01% of the existence of the species, the population grew to 6 billions.
Although we often regard the world of today as 'the normal world', this 0.01% is from an evolutionary viewpoint highly un-normal. Genetically, we are adapted to be hunter-gatherers in a spacious environment, not to the present situation. "
