2.4 Remember that most people will pretend to operate in your interest while operating in their own.
For example, most people will operate in a way that maximizes the amount of money they will get and that minimizes the amount of work they have to do to get it.
To see this, just leave someone unsupervised and allow them to bill you for what they have done. Be especially wary of this conflict of interest when people are advising you on matters that will affect how much money they earn—such as the lawyer who spends a lot of billable hours giving you advice, or the salesperson who advises you on what to purchase while receiving a commission on the amount that you spend. You can’t imaging how many people I meet who are eager to “help” me.
Don’t be naive. Strive for the highest possible percentage of your population having meaningful work and meaningful relationships while recognizing that there will always be some percentage of the population who won’t care for the community and/or will do it harm.
