If Muslims are concerned about their religion then there are many ways to fund Islamic activities and make it free of charge. For example, Muslims could set up a "bait al-maal" where all Muslims will voluntarily make donations (voluntary tax) and this could be invested to fund Islamic projects and give salary to the ulema. This is just a suggestion from the top of my head and there could be pros and cons. But if we are united and work together we can come up with many things. But its definitely possible.
