Smart people look to save money, spend less then they make, get great value and build wealth.
Joe Biden calls us terrorists.
Yes, saving and frugality are great, but there is a difference between that and having a society that simply stops producing and consuming. If nobody buys anything new, then how will people have the opportunity to buy something used? There is a time to save and a time to spend. Socialism destroys production and consumption and leads to the kind of hoarding and retrenchment we see today.
