Maybe people feel trapped, like it isn't worth sticking your head above the parapet, there's too much to lose.
A lot of music and other art now feels like it's to further a career option - maybe a bit edgy but not too difficult, got to keep paying the mortgage. This isn't really a criticism - I can see that pressure - the high cost of living, everyone set against each other, none of the old certainties of job security and so on.
Whereas uncertainty in the past might have bred creativity, now it seems to breed fear and conformity.
