NAFTA had little to no effect on manufacturing in America or on jobs (national pride isn't something you can measure, but that's a risible claim).
Here's manufacturing output since 1980. You can also look up the Industrial Production Output Index or longer timeframes for yourself.
With regard to the safety net, note that the vast majority of people in poverty in America (especially pre-transfer, but the statement applies to post, too) are people who we don't expect to work--children, the elderly, and the disabled. Plus, you have short-term unemployed (people who were laid off recently and will find work again soon, for example), and college students, as well as unpaid caretakers for the elderly and disabled, etc.
You might also note that Clinton's anti-poverty programs are directed at reducing unemployment (through infrastructure, for example), changing financial incentives, and reducing childcare costs (which provides parents more incentive to go to work and makes it easier for them to do so if they want to). Her college plan would also reduce poverty among college students, and certainly counts as "teaching a man to fish."
*I* would prefer to see more focus on cash transfers, but that's not actually what she's proposing. Trump also has talked about increasing infrastructure spending (good! though I don't actually have any confidence he'd do it), and nothing else, really.
