I concur with your observations. Enjoy the honeymoon period when everybody is on board and psyched for the change. Humans are such butterflies though! And then they turn lazy and resentful and try to find shortcuts. Like kids who never grow up. Then we have to have big blow ups to reset, or blow up and start all over again. 

Also throw the 80/20 rule into the mix, that is a big factor. The 20 are the consistent ones all he way through, but they cant hold back the 80 when it gets to the latter stages. 

Money is definitely a good rod. Seen good 'uns who lost their way  learn the hard way when their income is stymied as a result of getting caught out or deciding they know better and tried things their way. 

Need to have some sort of way to let the errants back in, on good behaviour.
