While I admit that at a first glance culture may not seem to have evolved as much as it should given that the 60s, 70s, 80s, and 90s all had their unique cultural tones.
In reality culture is shifting just as much as it ever has, just in different ways. Culture today is being fought socially with LGBT rights, ethnic integration and diversity, and the rejection of traditional values such as marriage and religion. This is such an issue that there is a political party dedicated solely to combat this (I assume you can guess which party). The Traditional America, White America, the one associated with the old times of baseball, apple pie, Christianity, and the nuclear family is losing power with many aspects of it dying off. More women are getting into the workforce, whites are increasingly becoming the minority, so rapidly that its very possible with in our lifetimes a majority of Americans won't be of European descent. People marrying in their twenties are becoming uncommon, gay marriage is pretty much guaranteed to be nation wide at this point and its only a matter of time until weed smoking follows suite.
All of this makes the segment of America that identifies the country as one that is a continuation of the 1950s and one that identifies the country as one that is a continuation of the 1960s. So to answer your question the counterculture in general seems to have all jumped into on giant pot the consists of the young, politically center and further left, and/or non-white. While the "traditional" culture has become one giant bulk of religious, xenophobic, center right and further right, and white.
Today we have a black (biracial) president, many states have legalized gay marriage, two states have decriminalized weed,nearly a majority of births happen out of wedlock, and it will only be a few years until the average age for marriage crosses 30 for both men and women. I will also add that many of this isn't due to sloppiness but more so because more people don't want to get married. None of this seems typical in the 1980s or even the 1990s.
