Dare I say it - might envy / jealousy towards another culture actually help the Arab world get out of this slump? It is precisely because the Arab world is so closed off - in terms of trade, in terms of cultural exchange, to Western cultural and economic ideas that this widespread poverty remains. This closure means that autocrats are able to pit Islam against Western ideals, constantly - we're bad, but we can stay in power as long as we're not
them, them being the decadent and greedy Westerners. Forget about the good ideals we bring - liberal democracy, decentralization of power. We haven't helped matters at all, what with our invasions, but to say it is just Western influence (which some are, not necessarily you) that has caused this morass, is oversimplifying matters and ignoring the huge role of religion and religious fundamentalism.
The fact that when given a chance to re-envision their society and culture, revolutionaries in these countries such as the Muslim Brotherhood keep choosing Sharia and other forms of theocracy means I think they will remain in a society strangled by the yoke of fundamentalist religion for the foreseeable future.
People in the Arab world aren't patients - they are agents, and have the power to change their circumstances.
