IF there are some kind of controlling 40 & 80 year cycles, then it seems that any governmental efforts to thwart them might be akin to revoking Daylight Savings Time so that the Sun won't be so hot.
More contemporary long-wave practitioners that incorporate Kondratieff would tell you that government intervention, while far far from a cure-all, is actually expected, natural, and necessary as one element to reset the cycle. In other words, without the gov't intervention (among other things) life would get so bad during the "Winter" or the "Fourth Turning Crisis" that there would be no "Spring" or "First Turning."
-- that's why these practitioners can look on World War 2 with fondness as actually the better, less stressful, road taken.
Just to note: for this 4T to come to a good ending, probably more important than gov't intervention is for most of us culture-war baby boomers to be eased out of any positions of authority in just about any walks of life.
