Does macroeconomics better support supply side or demand side economics?

Macroeconomics involves the study of how limited resources are utilized by an economy in the production of goods and services for consumption. Economies can be that of a state (regional), country (national) or even the world (global). The economic factors affecting the study include the total national earnings, the rate of employment, inflation and deflation rates, and the total worth of the goods and services produced in the state, among others.

Macroeconomics supports the demand and the supply side equally. For the success of an economy, both demand and supply are important. If only one element is supported, economic success will only be achieved partially. However, for the short run, more support is given to demand-side while for the long run, more support is given to the supply side. This is because demand creates its own supply for the short-run macroeconomic success while supply creates its own demand for the long-run macroeconomic success.
