It has gone up in the US.
The poor in the US are radically better off today than they were 40 or 50 years ago.
Medicaid only came into existence in 1965. Today, after decades of expansion, it covers the bottom ~22% of people in the US with free healthcare.
The Food Stamp Act came into existence in 1964. In 1990, 20 million people received food stamps. Today, after decades of expansion (including large expansions under the Bush Administration, an unpopular fact), it covers 40 million people. The SNAP program has gone from paying out $15 billion in 2001, to $63 billion in 2016.
The real per capita income transfer, for welfare policies, has nearly tripled since 1980. The US social safety net is almost infinitely better than it was in ~1967 near the peak of global US economic dominance post WW2. There was hardly any social safety net back then. And it's considerably better than it was in 1980 or 1990.
The cynics take this to mean the US economy is much worse off than in eg 1980 or 1990 (Rhetorically does that mean Denmark's economy is collapsing? Their welfare state is far larger than the US welfare state as share of the economy). That's not the case, the US welfare state has been expanded to include more people. That has helped push homelessness and poverty to near record lows currently.
