If capitalism breaks it will be to the benefit of very few.
Granted, capitalism needs maintenance.
Externalities need to be consistently reflected, so capitalism can optimize real value creation, instead of profitable value destruction. It is a tool that can be very good at either.
Capitalism also needs to be protected from corrupted government by, ironically, shoring up the decentralization of power so critical for democracy, including protecting democracy from capitalism's big money.
(Democracy and capitalism complement each other, in good ways when both operating independently in terms of power, and supportively in terms of different roles. And, ironically, also complement each other when they each corrupt the other.)
