There are tons of basic crud apps out there making people millionaires.
Name three.
Economics drives both demand and supply. CRUD apps are easy to make; the market for most CRUD-only apps is heavily saturated with competitors, so the differentiating value of your application is not likely to be your ability to perform CRUD operations. Put it this way - if you come up with a CRUD app that does something staggeringly valuable, expect strong competitors in days not years. Your chance to make millions is small.
