<human>:  What is the best retirement plan for someone with a low income?
<bot>: The best retirement plan for someone with a low income is to save as much as possible in low-cost, high-yield investments, such as stocks or mutual funds. Additionally, it is important to set aside money regularly, such as monthly or annually, into retirement accounts like 401(k)s or IRA. Additionally, taking advantage of the benefits from Social Security, such as receiving a monthly check, is also a wise choice.
