Well at the very end of the movie, Barbie chose to leave the system in it’s entirety. The movie has a revolutionary communist message, it’s saying true empowerment is impossible within the bounds of the system. It’s mocking the “more👏female👏executives” sentiment, just doing so in a way subtle enough the Hollywood financiers didn’t realize it.
Nah, the boom bust cycle happens due to the contradictions inherent to capitalism. They are speeding up because the contradictions get sharper as capitalism progresses. Marx developed this understanding 200 years ago, check it out:
“When the expansion of production outruns its profitability, when existing conditions of exploitation preclude a further profitable capital-expansion or what amounts to the same thing, an increase of accumulation does not increase the mass of surplus-value or profits, an absolute over-accumulation has occurred and the accumulation process comes to a halt. This interruption of the accumulation or its stagnation constitutes the capitalist crisis. It represents an overproduction of capital with respect to the degree of exploitation. From the point of view of profitability at this stage, existing capital is at the same time too small and too large. It is too large in relation to the existing surplus-value and it is not large enough to overcome the lack of surplus-value. Capital has only been over-produced in relation to profitability. This is not a material overproduction for the world in this respect is undercapitalised [73]. This stresses once again the central contradiction between the commodity as a use-value and as an exchange-value, between production for use and that for profit.” https://www.marxists.org/subject/economy/authors/yaffed/1972/mtccs/mtccs3.htm
