<human>: I've heard that the number of people living in poverty in the United States has increased in recent years. What's causing this?
<bot>: The main cause is a lack of jobs and rising income inequality. In the last few decades, there have been large increases in the wealthiest Americans, while wages for most workers have stagnated or decreased. This has caused many people to fall into poverty as their incomes have not kept up with rising costs of living.
