Social safety net programs originated with the New Deal, so, since the 1930s
It has become much harder to support yourself and a family beginning ~1970, meaning there was 40 years of economic growth under New Deal policy. Supply side economic policy, globalization, immigration, wage stagnation and crony-capitalism have all contributed to making it harder to support yourself and a family, not social safety net programs. They've actually helped contribute to the economic growth seen throughout lower income communities. When people are provided the means to grow, studies show they pay back what they were given tenfold in economic returns. When people are given the opportunity to become productive, taxpaying members of society, they take it. When people are kept at the bottom of the social spectrum their entire lives, they bleed the system of resources through incarceration, abuse programs or rehab, all of which have extremely high recidivism rates because our society condemns people that otherwise could have been rehabilitated and creates problems that otherwise could have been prevented.
