Problem with 'like'

[peteryoung]

Would you please help me with this problem? Thanks!

Vietnamese Amerasians did not have the foundation to succeed in this country [like] many other Vietnamese refugees.

My question is, what does this sentence say about 'other vietnamese refugees'? Does it mean that 'other' Vietnamese refugees also lead poor lives?
Or does it mean that they have some foundation to suceed in this country?

What if we insert a comma between 'country' and 'like'? Would it change its original meaning? If so, how?

I really appreciate your help.

Vietnamese Amerasians did not have the foundation to succeed like many other Vietnamese refugees.

Try,

[1] Vietnamese Amerasians, like many Vietnamese refugees, did not have the foundation to succeed in this country.

[1] Vietnamese Amerasians, unlike many Vietnamese refugees, did not have the foundation to succeed in this country.

The phrase 'many other' is suspect. Are all Vietnamese Amerasians refugees?
