Most people feel an ethical obligation to be productive. Some less wise people don't. Still others would like to be productive but feel doomed to a low-pay/low-reward career.
In fact, some people do have dim career prospects: If you're not bright, not driven, have personality issues, and excel at little, your chances of earning a good living aren't great in our ever-more-demanding global economy and with a U.S. empire that's likely in its decline and fall while China and India ascend.
Rather than guilt-trip you on the importance and wisdom of being productive, here I'll simply accept your self-assessment. I find anathema an able-bodied/able-minded person living off the taxpayer. I can more readily accept such people making the effort to become a stay-at-home spouse of a good income-earner. Agree to be a great spouse, homemaker, and perhaps parent in exchange for she or he providing the bulk of the family's income.
