Nowdays I'm just wondering which would be more business smart.....to offer people something they "want" or something they "need"...

More and more businesses are shipping work out of this country. Therefore, American's are losing jobs and income. Many have to be very careful as to what they "chose" to spend their hard earned money on. What are some "needs" out there that will be around for many more years to come? I can think of alot of things I would like to do that would be "fun" as far as a business, but I think people are clamping down on their spending habits for hobbies/entertainment purposes. What do you all think?

Thanks for your input.
God bless.
