How has the study of rhetoric helped to improve the social lives and linguistic skills of the people living in today’s world?i will like to...

What you propose is a major undertaking, so my first piece
of advice to you would be to narrow it down some. The study of rhetoric can cover
book-length works (PLURAL) and still not touch on all of the aspects that you have
indicated an interest in.

However, you mention an interest
in the importance of rhetoric and modern society. Integrating a little bit of history
into the equation, the way that we have historically viewed language usage has been
closely intertwined with social status. To put it simply, a lack of sold rhetorical
skills has generally been associated with a lack of intellect or education meaning that
the better able a person is to use language properly, the higher his or her educational
level and social status is usually viewed to be. Of course, this is stereotyping, but it
gives you a precedent and the precedent exists because generally, throughout history,
education at the higher than minimal levels has been restricted to the wealthy. Open
access to education for all is a relatively new
development.

Turning to the modern global society, although
educational opportunities may be broader, expectations have declined and along with them
the importance of language and rhetoric. Freedom of expression took a higher position
relative to the basic structure and form of language. Being creative became more
important than being an effective rhetoritician. Now, as we move away from an oral
communications dominated world into one in which the use of printed words is becoming
more important (as international businesses communicate in text based electronic form
daily) attention is truning back toward the importance of language and rhetoric skills.
This is being reflected to a degree in the educational system, but often it is not until
a student reaches college that it is given any solid
focus.

The way that language skills can be important in
today's society is that the better you are able to communicate the greater your ability
to advance in the world and to connect with people globally. Strong language skills are
something that employers look for, and the use of language is still a determinant of
social perception. People who are able to communicate effectively (without slang or bad
grammar) tends to present a first impression of a person who is educated and capable - a
person who is more likely to get the job or have the greatest impact on the largest
number of people (one of the reasons for Hitlers rise to power was his skill as a
rhetorician, Martin Luther King was able to reach the masses both black and white
because of his gifted use of language).
