Which of the following is least likely to contribute to economic growth?

Tighter government regulation is least likely to contribute to economic growth because, while regulations can be important for ensuring safety, fairness, and environmental protection, excessive or overly stringent regulations often impose additional costs on businesses. These costs can hinder innovation, reduce the efficiency of markets, and limit the ability of companies to grow and adapt to changes in the economy.

In contrast, technological advances encourage productivity and efficiency, which can lead to increased output and economic growth. Labor force education enhances the skill set of workers, making them more productive and potentially opening up new areas for economic activity. Increased access to resources supports economic expansion by ensuring that businesses have the materials and means necessary to operate effectively. Each of these factors generally promotes growth, while tighter regulations can act as a barrier or slow down the momentum of economic expansion.
