If they can't convince their current customers that (whatever) is the way of the future, then I'd argue they are NOT competent. Any fool can be a yes-man and keep doing what the previous guy did because "it always worked before".

Actually, STDs, crime, rape, junkies, and lost lives have been civilization's constant companion for millennia. There was definitely a tradition of pretending it wasn't happening prior to the late 60's/early 70's, but if you think people weren't getting high, screwing around, and beating the crap out of each other before then, and in similar numbers, you truly have no grasp of the history of humanity.

>Lifetimes centuries ago were 30-40 years on average. Only a handful of people lived 60 or more years. Today, many people live to 100, many more to 80

The average in previous centuries was heavily skewed by infant/childhood mortality. Plenty of people lived into their 80's back then. It's just that half of their brothers and sisters died before age 10, which dragged the average down. Still more succumbed to disease and infection before even middle age.

The average isn't going up because people live longer, it's going up because fewer people die young.
