What stopped the world population from hitting 8 billion in year 1 AD already then? Why did population of British Isles was under 1 million at the time, instead of over 70 million today? You can’t explain this without Malthusian arguments.
In a Malthusian model there would be a larger share of poor and starving as food becomes more abundant, because remember necessarily population outgrows food production.
The Malthusian model predicts forever growing extreme poverty as a share of population.
