Well, lets say you love art and get a business degree. How happy would you be making a good living but at the same time listening to mindless suits who love to hear themselves talk in boring ass meetings 9 HOURS A DAY.
Doing what truly interests you and being poor isn't a bad place to be IMO and this being the worse case scenario since CS folks usually do well financially.
If you enjoy technology/programming, you most likely will never be homeless if you get a CS degree. The "Good" employers see passion in potential employees and usually want these type of people.
