There are some people that do not need to go to college. First, there are musicians that have pop albums that have dropped out of high school and made it big. Billy Joel and Kenny Loggins are both high school dropouts that made it big in the music business. Some entertainers in other fields are able to do without college or even completion of high school.
The other major group that can dispense with college is those who are working beyond society's establishments. People that are developing and marketing alternative energy sources, setting up a new computer protocol, or those who are starting their own businesses may not need (or even benefit from) a college education. I wonder if Bill Gates, for instance, would have been able to get his software without a college degree had he been working on it from scratch (if it didn't exist before, then college is going to provide no guidance for developing it).
That leaves the other 99.9% of us who depend on business leaders for work. And, to get the better paying jobs, you are going to need college education. While those developing new infrastructure do not need college to do their job, those following them will need college in order to learn to use them to the full. And that is just about everyone.
To skip college just to pioneer is the ultimate folly. All those who can dispense with college without any negative consequences are already working independently, and the Watchtower Society cannot have any of that in its own ranks. Those who are dependent on others, like the Tower wants, had better go to college or they are in for dead end jobs with crap pay. Window washers do not make decent pay--and I wonder what they are going to do when companies decide that a little dust on the windows isn't that bad after all. (Or someone invents and markets windows that clean themselves). I think we are in for a lot of very poor Witlesses that are not going to have anything to spend on gas for pioneering during their senior years.
