The global economy is being run by capitalist oligarchs, whose central premises for existing are based on classical economic theories (private ownership of capital, extraction of resources, and exploitation of labor), their operational strategies are based on classical economic theories (infinite pursuit of growth at all costs, externalizing risks while internalizing profits, quarterly profit margins being the sole indicator of growth, cutting costs to minimize expenses and manufacturing scarcity to maximize pricing, etc.), and the policies meant to regulate and/or stimulate economic activity are based on classical economic theories (austerity for the poor, supply-side "trickle-down" economics for the rich including tax breaks, subsidies, and bailouts).

The tariffs are an exception attributable to the overt buffoonery of an extortionist grifter running the show. It doesn't negate all the other examples of how classical economic theory is destroying society and the planet.
