Islamic finance is the solution to a balanced and fair economy.
1. It prohibit interest to outlaw debt based exploitation and instead replaces it with loans of generosity (pay back exact amount, no interest ) or fund raising through investment. Whereby the risk of the person receiving investment is shared with the lender. This is in contrast with a conventional loan where if your property or business burns down, you still have to pay off the loan to the bank.
2. Zakat - a wealth tax on every Muslim. The value of 2.5% of cash, stocks, investment each year is given to the most needy of society.
Implement these systems and you will have a just economy that prevents hoarding and exploitation. Literally money is forced to move down societal class and acquiring more wealth is with increased risk. Islamic finance is the solution.
