Depending on one's perspective, there can be three major problems with this idea. One is that it requires society to expect things of people. The second is that in response to those expectations, some people may need to make some changes. The third is that some of the people who need to make changes will not do so unless society has a mechanism with which to put pressure on them to do it.

In this day and age, a lot of people get very uncomfortable when someone says things like this. Because of this, few politicians would dare to suggest these things: quite apart from alienating those uncomfortable with these ideas, rival politicians can capitalize on that perception to woo people who might not otherwise see any problem with what's being said. The end result is that speaking these things may be the closest thing there is to a sure-fire way to lose elections.
