So, he's lived here less than 15 years, paid nothing into "the system", and thinks he's entitled to collect bennies?
By way of contrast, on a couple of levels, Mrs. SVPete was a SAHM. But she worked before we had our first child, and has worked for several years, after our kids were more or less independent and after being the primary caregiver for her Mom. She is already eligible, except for her age.
if he doesn't like the US not wanting people who've not paid into the system drawing bennies, maybe he should go back to Oz.
