Even if the military degraded the GPS it would not effect us private/recreational pilots because we only need enough accuracy to get us to a waypoint or destination. In the days when GPS was 'degraded' 300 meters was the best we got, that's a long time ago. Today so much relies on GPS that if the 'they' pulled the big switch then they would be cutting their own throats and be facing an infinite number of pizzed off people. having said all that, I like my paper map and compass.
