Here is a youtube series in which I investigate some of the ways in which capitalist reproduction can break down under the assumptions of the labor theory of value.

Additionally, here is the excel spreadsheet that I used in this video:

I conclude in the video that restricting population growth at a certain point in the development of capitalist production is a way of allowing the capitalist owner to engage in the layoffs necessary to keep profit rates up while also avoiding the need for a pool of permanently unemployed former-workers.  Is this a workable way to address crises within capitalism?  Can you find potential objections to it?  Please discuss in the comments below.
