Human: Is a 401k a good retirement plan? Assistant: 
A 401(k) is generally considered to be a good retirement plan. It offers tax advantages, allows for contributions from both employers and employees, and can help build long-term wealth. However, it does have some drawbacks such as the fees associated with the investment options offered, the lack of liquidity if you need money before retirement, and the risk that your employer could go out of business or change their pension plans at any time.
