When we start talking about 24% of the GDP we gotta go more specific into what industries depend on to understand the impact. Agricultural industry as a whole (imports, local production, etc.) represents much less than 24% of USA's GDP but if it disappeared it would be cataclysmic for the nation.

And 24% of GDP is a whole fucking quarter of the whole economic production of the largest economy in the world, it's not a "mild recession"...
