The gap doesn't just "seem" high, it "is" high. The core reason this is a problem is that higher gaps in income in a society are correlated (not necessarily causal, but they frequently appear) with social instability.
As voters, we currently want more America than we've proven willing to pay for. This means one of 2 things must happen.
1. We pay more for the America we have
2. We get less America than we want
"less" in this case could mean really obvious things like less services or benefits of certain types. It could also mean less of intangibles/unquantifiables such as social stability, or opportunity etc, which are hard to value until they're not there (I've spent much of my life in seriously unstable places in the world, and I can attest that little else works when you dont have the basics). Most likely, we'll have to pay a little more, accept a little less, and as OP suggests, buy slightly different things with what we're paying. If we don't make those decisions, gravity will make them for us.
