<p>“why do we need to be well-educated?”</p>
<p>a) So people can’t take advantage of you as easily.
b) Because knowing about the world is inherently valuable.
c) More knowledge helps you make more intelligent decisions on how to live your life - what religion to follow, for example.
d) Well-educated people are often less prejudiced.</p>
<p>Of course there are more questions you could ask about why it’s good that people not be prejudiced, or why knowledge is inherently valuable, etc.</p>
<p>What does it mean to be well-educated? Well, I don’t know. That’s why I recommended it as a question. Presumably it would include knowing stuff about other cultures and their languages. </p>
<p>Benefits of learning a foreign language:
a) It improves your English skills.
b) You could go live in another country and get a job there, if you wanted.
c) Presumably you’d have a better experience as a tourist in other countries if you could understand what was going on around you.
d) Employers like it.</p>
