How does a society build on what it values while ensuring that it stays true to the original beliefs

for examples on the way you would run things based on some values:

If you value integrity and you experience a quality problem in your manufacturing process, you honestly inform your customer of the exact nature of the problem. You discuss your actions to eliminate the problem, and the anticipated delivery time the customer can expect. If integrity is not a fundamental and core value, you may make excuses and mislead the customer.

If you value and care about the people in your organization, you will pay for health insurance, dental insurance, retirement accounts, and provide regular raises and bonuses for dedicated staff. If you value equality and a sense of family, you will wipe out the physical trappings of power, status, and inequality such as executive parking places and offices that grow larger by a foot with every promotion.
