QUESTION 1:

There can be no doubt that inequality in the United States – the
wealth of the wealthy as compared to the average income of the average
citizen of the United States – has increased spectacularly since the
1970s.  What does Professor Kane believe to be the main causes of this? 
What do you believe to be the main causes of this?

QUESTION 2:

Do you believe the rise of globalization and increased inequality in
the United States have created a stable environment for democracy and
liberty to thrive?  Why or why not?

QUESTION 3:

Watch the Harvard Inequality Study video linked to in the Inequality
Lecture Notes and discussed in a Professor Kane Lecture Video on
Inequality.  How is the average American misunderstanding inequality in
the United States?  What does the average American believe would be the
ideal income and distribution of wealth structure in the United States? 
What do you believe would be the ideal income and distribution of
wealth structure in the United States?  How does the actual current

QUESTION 4:

In Lecture Videos, Professor Kane asserts that too much equality can
wreck a market-based economy as there is little incentive to work hard,
be innovative, and be productive.  In Lecture Videos Professor Kane also
asserts that too much inequality
can cause there to be little incentive to work hard, to be innovative,
and to be productive thereby leading to a collapsing economy.  How so? 
Which of these two processes, if either, can be seen at work in the
American economy today?
