Like I versus Like me [duplicate]

My friend and I got into an argument about English grammar, so I was hoping maybe you could help us out. Okay so we want to know if the following part of the sentence is correct, "People who are satisfied and feel self-fulfilled like I" rather than "People who are satisfied and feel self-fulfilled like me". I have already provided many sources to my friend showing that the first way is a formal and a grammatically correct way, however he wants an answer with this specific part of the sentence.

Please help us out

Thank you

Solution 1:

Like acts as a preposition, and its object takes the objective case if it is capable of encoding case.

People like me who are satisfied and feel self-fulfilled ...
People who are satisfied and feel self-fulfilled like me ...

Like I occurs only when I is not the object of the preposition but merely the subject of a clause which is the object of a preposition.

People who are satisfied like I am ...
People who feel self-fulfilled like I do ...

In formal registers, however, you should be using as here, rather than like.

People who are satisfied, as I am ...
People who feel self-fulfilled, as I do ...
