I agree. Even now (2012 - almost 2013) there are still lots of services needed but when I was a teenager I unfortunately kept looking for a type of job that my friends had instead of looking for a need to fill (I eventually did land a very different job though working alongside field workers).
Today I've seen adults in their 30's and 40's jump out of the IT industry to start their own business scooping dog poop out of back yards and making enough money to live on. Same thing with cleaning swimming pools. There are lots of services they could provide.
