Ask Marilyn: IQ vs. the economists

Marilyn vos Savant has (supposedly, read the link) the world's highest recorded IQ at 228.  She is now fielding questions on economics.  Here is one example:

Question: Why has the income disparity
grown so much in developed countries? – Matthew Cencich, Victoria,
British Columbia, Canada

Answer: I think the disparity is
a normal result of overall economic growth. The bottom incomes (zero)
can’t go lower, but the top incomes can go up and up. And so they do,
of course.

Here is another:

Question: Do you think that government
actively encouraging people to borrow money (and spend it) is the right
way to resolve the recession? – Caroline Kelly, Hendon, London

Answer:
No. I think that more consumer activity could be modestly helpful to
the economy in the short term. And in better times, it would even
masquerade as growth. But in the current climate, increasing the family
debt would cause added personal financial problems. So I doubt that
it’s useful for government to advocate shopping as a form of national
service unless elected officials are perhaps a tad more interested in
shifting a little of the burden away from themselves than they are in a
lasting solution.

She also explains the financial crisis. ("First, an economy based on growth is bound to falter now and then. A
whole sector could collapse. It’s a house of cards. Eventually, it must
morph into a system that functions on stability, or it will fail –
meaning a fall large enough to cause an unstoppable breakdown and
widespread hardship.")

Question: on these problems, does she do better or worse than leading economists?

Addendum: Here is Marilyn on YouTube.  Oddly (look just past the 4:00 mark), she can't define IQ properly.
