Opinions about spending on health show a distinctive pattern: a trend towards support for spending more through 2008, and then a sharp move in favor of spending less. The reason for that seems pretty obvious: "Obamacare" was passed in 2010.
Finally, the two general opinions:
It looks like there was a more in a conservative direction in the first few years, from the early 1970s to the early 1980s, and no obvious trend since then.
Opinions on these questions generally are more conservative when a Democrat is president, and more liberal when a Republican is, which makes sense since all of them refer to the way things are as a baseline. If you regress each on a dummy variable for the party of the president and a time trend, the estimate on the time trend is negative and statistically significant for spending on the environment, social security, conditions of blacks, welfare, and aid to the poor, and not significantly different from zero for the rest. So in general, it seems that people have become more generous and accepting of the welfare state during the period of rising inequality.
This raises a number of questions which I don't have time to address now, but will get to soon.
