when you buy a business, you see there's potential growth in investing there. The point of having a business is to generate good profits (basically, sales minus all expenses, taxes, etc).
Operating expenses just like what you said are necessary for the business to run (that's why they are called operating expenses, without them, you can't 'operate' your business and thus, wont be able to make sales). If your expenses are higher than your sales, then that would pose a problem.
r u serious, if people asked that of any buisness we wouldn't have movies..
