ELI5: paradox of thrift

// eli5

What is the paradox of thrift?

The paradox of thrift is when saving money seems like a good idea, but when everyone does it at the same time, it actually hurts the whole economy [1][2]. It's like if everyone in your town stopped buying ice cream from the ice cream shop to save money—the shop owner would have less money to pay workers, those workers couldn't buy things either, and soon everyone is worse off [2].

Why does it happen?

One person's spending is another person's paycheck [2]. When you spend money at a store, the store owner gets paid, and they use that money to pay employees and buy more stuff to sell [4]. But when lots of people save instead of spend during hard times, businesses make less money and have to lay off workers, making the hard times even worse [3][5].

What does it feel like?

Imagine everyone in your class decided to save their lunch money instead of buying lunch—the cafeteria would have no customers, the cafeteria workers would lose their jobs, and people would be hungry AND broke [5].

How do you fix it?

Governments can help by spending money during recessions to keep money flowing through the economy, even when people are saving [3]. This keeps businesses going and workers employed until people feel confident enough to spend again [2].
