Your friend might be a charismatic opportunist, but your game group doesn't seem to mind. We all know people that never contribute food or beverage to parties, or never have money when it's time to split the restaurant check or bar tab....but that's not what Romney's 47% comment meant.
You didn't pay
federal income tax for quite a while, even when you were "working". Either you were a student, among bottom rungs of employment-income, starting your family, or a first-time home buyer. According to Romney (et al) you are a
moocher: you would never become
self-sufficient or self-reliant; you'd always expect "entitlements" or FREE STUFF; and he could never gain your vote.
He was quite wrong, of course, because we all know you voted for Romney. But he may have been right about your "mooching". You used lowest federal tax liabilities to your best advantage, and expect "entitlements" from your state (in-state university tuition, maybe low cost loans), your employer (health insurance subsidies, 401-K matching contributions, etc.)
You're "mooching" off preferential tax codes and corporate croneyism, while whining about "Welfare".
