How and who is he cheating? You think he's not paying taxes? You think he's contributing to overloaded social services? From what I can tell he's not working under table. (i.e. taxes are being withheld and paid on behalf of whatever social security number he's using.) And he obviously was unable to avail himself of college financial help due to his immigration status, so it seems pretty unlikely that he's able to be a drain on many other social programs. So how he is cheating me?
