The basic premise of Moral Foundation org is the unproven theory of Evolution. And evolution is claimed to be an upward climb, hence there cannot be a moral decline, as you also believe citing some census data. Yet we know that what is reported always need not reflect the truth. It was when the census-celebrated good news (that moral decline is a myth) came that the former Pope decided to resign as he could not cope with the moral decline he personally witnessed among his own people.
Moral decline is not a subject of dispute, you only need to open your eyes to see whether people are going upward or downward. To mention a few:
1) People know that when income come decreased, they should cut down the expenditure. This sensible course is not followed in the most important area of life. People know that earth’s resources are depleting fast and cost of living is sky-rocketing, yet most people zealously engage in a spree of increasing population (which is at the root of all major problems on earth), rather than cutting down the number of population! This is nothing but utter disregard for the welfare of future generation—what morality is this?
2) People know prevention is better than cure, yet most people prefer cure to prevention! ‘My desires should be fulfilled at any cost here and now no matter what happens to me in the future’ is the attitude behind such a course—what morality is this?
3) Science (which is praised as a savior of mankind) has been giving us many comforts and but also created things to destroy all those comforts and even the very earth itself several times, and has given button into the hands of politicians who have the history of fighting not only ordinary wars, but also TWO world wars! ‘We should get the short-term profit from arms-sale no matter how many starve to death around the world’ is the attitude behind this—what morality is this?
4) People encourage all types of innovation on the gadgets they use (compare today’s cars, mobile phones, computers … with those of the past years). Yet no one is interested in innovating more important things such as their beliefs about religion, politics, language …… (ancient languages such as Sanskrit had 96 words for love depending upon the object of love—eg. One word for love of God, another word for love of creature; one towards wife, and another for someone else’s wife….. No wonder NASA found only this language suitable for developing artificial intelligence) Why was such a superb language was replaced with inferior language as the so-called evolution progressed?
