<human>: What are the advantages of having a 401k?
<bot>: The primary advantage of having a 401(k) is that it allows you to save for retirement early on. You can contribute as much as you want, and the money grows tax-deferred until withdrawal. Additionally, employers often match contributions up to a certain percentage or dollar amount, which increases your savings even more. Finally, 401(k) plans offer a wide range of investment options, so you have more control over how your money is invested.
