Do “as with” and “ as is the case with” mean the same thing?
As with many men, he seemed to be having a midlife crisis.

Hi. What’s up, everyone?
Why doesn’t the above example work?

And generally, do “as with” and “as is the case with” mean the same thing? If not, could you please give some examples to illustrate your idea?

Thank you.

Answer

"like with many men"
or 
"as is the case with many men" 
Both = the more common way to say the sentence
BUT "as with many men" is ok and understood it is just a shorter contradicted version, no need to specify "the case" the listener will understand this.

Answer

It seems like there is an error 'as with' should be replaced by 'like'.  'Like many men' (saying that many men suffer a mid-life crisis). However, you would need to check the sentence with the previous one in the text to understand the context better.

'as is' in not used much however 'as is the case with' is more common.
