We have to remember too, that we are talking percentages. The percentage of the population may be less, but the actual number of hunters probably has not decreased all that much. That said, I do see a lot less kids doing it than when I was young.
Bravedeer, I am not sure why you put white in the comment about work. The statistics are clear on non-white population growth and that hunting is predominantly a white sport. The kids I am taking hunting are black and they took to hunting very quickly. But yes, if more Americans, white, brown, black, yellow, green, or some combo of the above, were willing (or better yet, had to work to eat) to do manual labor then maybe there wouldn't be so much work for others. Or, if there were not so much cheap immigrant labor, then the demand for workers would go up and so would wages and maybe Americans would do the jobs. And, lol, I actually hunt with a few metrosexuals. They wear rubber gloves when the gut stuff so they don't mess up their nails. .just kidding.
