The Malthusian argument is incorrect and I disagree with the concept of physical infrastructure being the end-all-be-all. Japan, South Korea, Germany, as well as the USSR had explosive growth after WW2 not because they had massive existing infrastructure, but because of social systems & processes that enable a reliable, stable, productive society. If the societies are fragile (vulnerable to drought, markets, or violence), or rotting (corruption, superstition, tribalism), even great infrastructure can make for subpar growth. An analogy I always think of are Wadis (dry riverbeds); in very dry places with little rainfall (like Hudaydah in Yemen / Saudi Arabia), when it DOES rain, the dry dirt riverbeds don't soak up any water and transport it all out in flash floods - but it IS possible (and has been done) to invest in the land's ability to hold that water rather than purge it. Similarly, in a "always-developing" society, there'd have to be a investment in the people to ensure they can benefit from solutions to their issues.
