"and so many people are cheated out of shit loads of money in the name of spirituality." Yes, and that's not right. But it doesn't make spirituality any more or less true. People are cheated out of a shit load of money in the name of science too. Think of the malpractices of big pharma, or the many supplements sold in the name of science while there's no evidence at all or scarce evidence that such supplements even work and don't do more damage than good. Neither do such practices make science any more or less true.
Spirituality definitely exists, as many people claim to be spiritual and practice some form of spirituality. It would make as little sense to ask if religion exists, because we can clearly observe its existence.
What I think you wanted to ask if is spirituality is real or not. This question would be difficult to answer since there isn't one clear and agreed upon definition of the word. To a religious person who considers himself spiritual, spirituality means something entirely different than it would mean to someone who considers themselves spiritual, but not religious, or someone who is a spiritual Pantheist for example. The religious person would consider their spirituality to be his or her relationship to a supernatural being of which we have no evidence, and the latter would in his spiritual philosophy fall more along the lines of Einstein and Carl Sagan, and would take his humble position as being part of an infinite universe filled with mysteries to be uncovered. And while science certainly provides us with our best guesses, in the end we can never be 100% sure what is real and what is not. Science deals with likelihoods, and some guesses just seem a lot more likely than others, based on the evidence we've gathered. Now let's just hope that our senses aren't deceiving us and we're really not just brains in vats suffering from mass hallucination.
"“Science has beauty, power, and majesty that can provide spiritual as well as practical fulfillment. But superstition and pseudoscience keep getting in the way, providing easy answers, casually pressing our awe buttons, and cheapening the experience." -- Carl Sagan
"Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light-years and in the passage of ages, when we grasp the intricacy, beauty, and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual ... The notion that science and spirituality are somehow mutually exclusive does a disservice to both. " -- Carl Sagan
