I do agree with you that it's a myth that extravagant overspending is what keeps the economy going.
Agreed, but the typical household is not using debt as a prudent tool in building wealth... THere is a huge difference between borrowing money to buy a truck for your business that is going to make you an extra $100k a year, but cost you $25k a year in payments.... and buying a large screen TV for 2500 on credit at 18%, and paying back $5k for it.
I am not arguing that debt can be used to create wealth, but I am very much arguing with the Myth that debt spending is good for the economy.
