Which of the following financial strategies is often highlighted as a key to wealth building?

Paying down high-interest debt is a key financial strategy for wealth building because it directly reduces the amount of money you spend on interest over time. When individuals carry high-interest debt, such as credit card debt, they incur substantial costs that can hinder their ability to save and invest for the future. By prioritizing the repayment of this debt, individuals can free up more of their income, allowing them to allocate funds toward savings and investments that generate wealth.

In contrast, investing in collectibles often carries higher risks and may not yield consistent returns, while buying expensive cars can lead to depreciation and additional financial strain due to maintenance and insurance costs. Frequent credit card use can exacerbate debt levels, particularly when balances are not paid in full. Therefore, focusing on reducing high-interest debt creates a stronger financial foundation and provides the opportunity to build wealth over time.
