Final answer:
The flaw in the individual approach is that what is in the individual's best interests may not be in everyone's interest in the long term.
Step-by-step explanation:
The flaw in the individual approach is that what results in the individual's best interests is not always what is in everyone's interest long term. This statement is true. While pursuing one's own self-interest may benefit the individual in the short term, it may not align with the best interests of the broader community or society as a whole in the long run. An example of this can be seen in the tragedy of the commons, where individuals acting in their own self-interest may deplete shared resources, leading to negative consequences for everyone involved.
Another example is the concept of collective action problems, where rational individuals making decisions based on their self-interest can end up harming others and themselves in the long term.
