There is no single business which is best at all points in time. All businesses have phases of high & low growth depending on industry life cycle and geography. Currently in India, laundry and dry clean business presents a very profitable business opportunity because 96% of the industry is unorganized and competition level is low. Plus, with population in urban apartments growing significantly, as well as more and more females preferring to be working professionals (and not housewives), laundry business is set for a huge growth phase over next 10 years.
