I guess the idea isn't that different to what happened in the Christian world - much of the wealth of the people was directed towards building elaborate and large churches, with much of the money heading south to the most elaborate and powerful of them all - in Rome
Given that there were something like over 400,000 muslims in the country in the 2000 census and they have just four mosques - surely those mosques should be so rich that there should be minarets spouting out all over the place?
