This is the worst thing that I have ever read, so bad that it made me make an account just to tell you how wrong you are.

First of all, if you even, for a second, thought about what you were saying this immediately crumbles. You dedicate a significant portion to talking about the material differences in the lives of those individuals, the property they own, the health care they can access, but then proceed to deny that it is the material conditions, that you have just laid out, that drive people towards certain ideas! You utterly contradict yourself.

Secondly, you just completely ignore how reality works and draw an arbitrary start line where everything just begins in a highly developed manner. The workers are not preordained to be workers, the bourgeoisie are not preordained to be such either. The people in your thought experiment would be in such a position due to a very very very very long history of subjective action arising from objective material conditions and social relationships (those relationships also arising from material conditions). So, dialectical materialism is very aptly named!

Thirdly, you have no idea what dialectical means and it is agonisingly obvious. A dialectic is the relationship between the opposite aspects inherent within a thing. So, with any morsel of philosophical thought it is readily apparent that “dialectical determinism” is an oxymoron. And I know you lack that said morsel of philosophical thought, so I’m going to explain it to you. The dialectic in question is the subject-object relationship, otherwise known as historical materialism: so if you remove subjectivity (which is a necessary consequence of a deterministic world view) you are debasing the subject to a mere object; and if there is no subject, there’s no subject-object relationship and thus no dialectic.

To wrap things up, stop trying to talk about things you’re beyond clueless about!
