How can the simple employee keep pace with those who earn tremendous profits from the global stock market and secure a subsistence living, and is it time to establish a global Islamic economic system?

What you have mentioned about the disadvantages of stock markets is correct, and the Islamic alternative is to invest money in permissible matters such as buying and selling (trade) and Mudarabah (definition) (profit-sharing), or in the financial market with Sharia (definition)-compliant regulations. This creates job opportunities and reduces inflation. We call upon Muslim traders and economic experts to develop economic programs and comprehensive plans for financial transactions according to Sharia regulations. As for those with low incomes, we advise them to fear Allah and practice asceticism in this world, and there is no blame upon them for seeking legitimate ways to earn money.
