The opposite is true. Before the mathematics, everyone in macroeconomics was hopelessly confused. The mathematics makes the claims people are making much clearer. People still argue about what Marx meant in Capital. Nobody argues what Kydland and Prescott meant in "Aggregate Fluctations and Time to Build" (an early mathy path on macroeconomics), because it's all right there in the math.
