Does poverty play a role in why men become involved in terroism for al Qaeda?

As you can see from the two links below, we simply do not
know whether poverty plays any major role in causing people to get involved in
terrorism.  There are people who believe passionately in the idea that poverty does
cause terrorism, but there are also people who reject that
idea.

Those who believe that poverty causes terrorism argue
that people become terrorists out of frustration.  They are not able to get ahead
economically in life and this makes them frustrated and angry.  They are therefore easy
prey for charismatic leaders who can persuade them to go off and engage in terrorist
attacks.

However, there are those who reject this
argument.  As one of the links below says, people who end up getting involved in
terrorism are not typically poor people.  Instead, they are often people like Osama bin
Laden who are actually pretty well-off.  To quote from the
link:

But the
empirical record evinces little correlation between economics and militant Islam.
Aggregate measures of wealth and economic trends fall flat as predictors of where
militant Islam will be strong and where not. On the level of individuals, too,
conventional wisdom points to militant Islam attracting the poor, the alienated and the
marginal—but research finds precisely the opposite to be true. To the extent that
economic factors explain who becomes Islamist, they point to the fairly well off, not
the poor. . . .

So, the
answer to this is that we simply do not know because "experts" make arguments on both
sides of this issue.
