Well that strategy works, till it doesn't. There is a difference between being rich and being wealthy, and that is sustainability of wealth. You can live your life and still contribute to long term wealth growth. What if you need to pay for some big unexpected expense, like your pet getting sick or you getting in an accident? Without proper financial backbone, even one of those type of incidents can throw you off and take you down the rabbit hole of catching up with debt.
