Capitalist economic systems are typically more productive in the amount of resources they develop.
In a socialist economy, the government controls the means of production. This means they would determine how many goods/resources are needed for their citizens. However, in a capitalist society, the amount of goods/resources produced is dependent on the wants of the consumer. This allows businesses to curtail their production to the needs of the citizens rather than the government.
