I am just going to repost what I posted in a debate about Hitler's motivations.
The Earth has a finite amount of resources. There is only so much oil, food, trees and many more valuable things to go around. A man named Thomas Malthus in the late 18th century observed that the human population could increase and an exponential rate (ex. 2,4,8,16,32) while food production increases at a more linear rate (ex. 1,2,3,4,5). [1]
What happens when population exceeds our abilities to create enough resources are what Malthus refers to as positive checks. These checks include (war over resources, famine, or disease due to things like more condensed and close together population (ie. Covid19). The other option Malthus brought up was preventative checks such as encouraging later marriages, making abortions easy to access and promoting and encouraging homosexuality.
Hitler seemed to be applying Malthusianism to his policies for Germany. in Mein Kompf Hitler states;
"The annual increase of population in Germany amounts to almost 900,000
souls. The difficulties of providing for this army of new citizens must
grow from year to year and must finally lead to a catastrophe, unless
ways and means are found which will forestall the danger of misery and
hunger." [2]
As you can see, Hitler was very concerned about the Malthusian dilemma. according to an article by Bryan Caplan writing for [econlib.org](
http://econlib.org) [3] Hitler went on to weigh all of the options Malthus presents and then states;
"Of course people will not voluntarily make that accommodation. At this
point the right of self-preservation comes into effect. And when
attempts to settle the difficulty in an amicable way are rejected the
clenched hand must take by force that which was refused to the open hand
of friendship. If in the past our ancestors had based their political
decisions on similar pacifist nonsense as our present generation does,
we should not possess more than one-third of the national territory that
we possess to-day and probably there would be no German nation to worry
about its future in Europe." [2]
I assume that con will of course agree with Hitler about the right to self preservation, so I won't digress into that. As we can see from Malthus and Hitler, Germany was headed for disaster and their right to a good life would soon be taken from them, if Hitler was not going to be proactive.
**Lebensraum**
Hitler had a plan to deal with this Malthusian disaster, swiftly heading towards Germany. An overall plan to preserve his German people that involved taking preventative measures as Malthus had suggested. Hitler would go on to reduce the world population by 60 million people and push back a global Malthusian disaster. [4] A population that could easily double every 25 years. That would be 3 doublings by now and an additional 180 million current people. Despite how much Hitler helped the globe, his main mission was to do right by the German people he led. Seriously about 800 million people are currently starving to death. If not for Hitler it would most likely be 1 billion people. [5]
Lebensraum (meaning living space) was an answer to the Malthusian problem of population growth exceeding resource growth. It was a philosophy of conquering other parts of Europe so that way Germans could live more spread out with more resources to sustain their population. There is something else to consider about Lebensraum before we move forward, but first a better definition of lebensraum from chat GPT that is lightly edited by me to remove it's anti Nazi bias.
"The Nazi philosophy of Lebensraum, which means "living space" in German, was a belief held by Adolf Hitler and the Nazi Party that emphasized the expansion of German territory by acquiring more land in Eastern Europe. The Nazis believed that the Germanic people, needed more living space to grow and flourish, and that acquiring land in Eastern Europe was necessary for their expansionist goals." [1]
