The correct answer is "more."
When workers earn high wages, they can exchange this extra money for more goods and services., which they will do provided that they have confidence in the economy.
One of the good things about a stable economy is that it generates income for everybody. If employers are able to pay more to their employees is because they are selling more products and services. This people trust the economy and are spending their money. When companies pay more and the workers earn high wages, they can spend extra money on other goods and services of other companies, helping the national economy.
