In order for north america to operate as healthy economy, what do individuals need to do to contribute to the success of the country? how is our economy impacted when people make bad financial decisions?

High employment is a good way to keep our economy healthy, along with price stability. An example of price stability would be the following:
Someone would steal an item at a store. They keep coming back to steal more and more until the store begins to notice. This makes paying workers more difficult, as there isn't much profit to be made with the limited stock. This makes workers quit, causing less cash flow into the economy,.
When we make bad financial decisions our economy is effected in the following ways:
Someone could take a loan, become unable to pay it back, and get into a financial debt. It becomes worse and uncontrollable the longer it goes unpaid. Eventually this debt may lead to bankruptcy.
