In my opinion, If you ask too many ‘why’ almost every business will start to sound useless. There is no immediate need for most of the products where the majority of the funding goes. But it is the capitalistic vehicle on which the economy booms, and a booming economy funds a lot of useful projects and elevates the living standard for everyone.

Since, by this definition all businesses are useless, corresponding jobs will sound pointless too. But you can always find something interesting to work on while on a job. Don’t forget you are in-charge of your career and there is plenty of time to shape it the way you want.
