Final answer:
Lower tax rates for the wealthy can incentivize investment and economic growth, and wealthy individuals may contribute through philanthropy.
Step-by-step explanation:
When discussing whether it is sometimes a good thing that rich people often do not pay much taxes, one argument is that lower tax rates for the wealthy can incentivize them to invest, innovate, and create jobs, which can stimulate economic growth. This can result in higher incomes for everyone and an overall improvement in the economy. Additionally, it is argued that rich people may already contribute in other ways such as philanthropy, which can help address social issues and support communities.
