yes and no IMO. Slang, I feel, was more an invention of men, in both middle and lower class. Mostly soldiers and sailors, who, when separated from women, became more "crass". Evidence today (and in the past) is the reluctance of most men to use many profanties around women and family.
I find swearing is the mark of a limited vocabulary
Maybe, maybe not. Under the force of overpowering emotion, one could have a literary Nobel-winner's use of words, and yet only the more earthy expressions will seem to express one's state of mind.
The frequent use of bad language would then indicate not a lack of vocabulary but an emotional system that frequently allows emotions to become "overpowering." And like everything else in our life, the emotional functioning is more than half biological.
This reminds me of an old (clean) joke:
A lady was trying to persuade her Navy-officer husband that he needed a thesaurus. "In all of your official reports," she asked; "don't you sometimes not know the word you need?"
"If I don't know the word I need" her husband answered, "I use another word already in my mind."
"But aren't there times," she persisted; "when only a specific word will serve?"
"Honey," the man retorted, "the Navy doesn't allow those words in our reporting".
