waste of time and money?

If you were to do cost up the value of advertising done by companies who had no idea of the reason, message, or value of their advertisements, the numbers would be astronomical.... why do so many companies focus on what rather than why? It's the busy stupid people who get the most done on this planet because we're taught that actions are worth more than words. The real lesson needs to be that words without actions are worthless... and there's no point advertising until there's something to say that can be followed up with action.
