How is social studies an element in uplifting human values in a given society?

The best way for social studies to "uplift human values"
is by presenting examples from history or from the modern world in which the benefits of
having "good" values are shown.  Outside of that, the task of "uplifting human values"
is better suited to subjects like religion or
philosophy.

In social studies, we study human societies,
how they are put together and how they work.  If we wish to inculcate values such as
democracy and tolerance in our students (and thereby uplift them), we can use social
studies to present evidence that societies with such values are less likely to engage in
wars or to commit atrocities against their citizens.

In
this way, we can "uplift" our students values by giving them examples of how those
values are beneficial.
