It doesn’t.

1. Classical economics is very limited – it does not even try to deal with behavior over time. Classical economists believed (faith unsupported by either theory or data) that the forces would act so quickly that there would never even be recessions (two quarters of decreasing GDP)

Since, of course, reality has indicated that there are recessions, something had to give. That’s why economics has advanced beyond the classical. Those who want to cling to as much of the classical theory as possible are the new classical economists.

2. One frequently used excuse was Say’s law.

But Say’s law is so obviously wrong that even Say himself saw that the law was wrong:

That doesn’t prevent people from clinging to it:
