The Muslim Brotherhood thinks that Islam is the answer to price inflation. This makes perfect sense because Islam is always the answer regardless of the question! As Robert Spencer points out:
Of course Islam is an economic solution, because in the Qur'an, obedience to Allah brings prosperity. So if Egypt is suffering economic woes, it is because it is not Islamic enough. And if Egypt does become an Islamic state and still doesn't prosper, the Jews are always there to blame.
It's a win-win!
