Imam Khomeini in this regard said as following:
Even the materialistic will become spiritual.
Do not think too highly of the West.
There is no basis for humanity there. It is the West which is eradicating the bases of human ethics. It is the West which is trampling upon human dignity. But we imagine that the West possesses everything.
Now that the West enjoys the automobile, so it ought to have everything. But in laws, our laws are richer than those of the whole world.
