This is a little complex.
This is an example using both em dash and comma. Please do let me know whether both forms are okay.
1) He tried to create a little wealth—and a little security—in that situation.
2) He tried to create a little wealth, and a little security, in that situation. (the reason for comma is because I want a pause after wealth).
What I mean is: em dash creates a nice pause and THEN we add 'a little security' right after that. Can we also use comma in its place to create a similar effect?
I'd use the em-dash, but it's just a matter of style which one you choose.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
