Quite unfortunately, I think, given a choice, most people will tend towards doing as little as possible to survive --not all people, there are some who just want to create and others provide services (volunteers come to mind).
It takes community and building mindset to fend off the tendency toward minimum level survival. It takes having a certain ethic to transcend that. Of course people don't want to plough in the muddy soil and tend to sick animals and harvest in the heat, if they can get away with it. If they instead could drink, get merry and play all day, many will chose that option if not inculcated otherwise.
Who knows, maybe we will go back to permanent mediocrity by most once the drive to succeed is removed.
A progressing society needs constant effort to keep it alive. It's not self-perpetuating by itself.
