It is known as the Revisionism. Inside the Marxist development, the word revisionism is utilized to allude to different thoughts, standards, and speculations that depend on a noteworthy modification of principal Marxist premises.

The correct rule is "a person could not marry a person of lower social standing."
If you are born into a lower social class & became wealthier, had good behavior, owned more land, etc., it wouldn't change your position.
You are going to be stuck with the same social class your entire life, same thing would happen if your parents were in the lower social class & you became more successful, you would still be in the same class as your parents. You would work the jobs they worked & go through what they have to go through. Though I believe later on it was socially acceptable to marry to a lower class, but it was taboo.
Hopefully this helped of some sort!
