Preliminary sales figures show a very low growth rate for retailers this Christmas season that is likely to be the lowest since 2008. It's not too hard to figure out why this is so, people are getting lower wages and so have less to spend despite increased consumer debt.
It's not that there isn't enough business activity, corporations are showing record profits and the rich are swimming in cash, they just keep it for themselves. In the old days, when cash hoarding really started to tank the economy, people called this occurrence a 'cash shortage'. Today economists call it a recession when it meets their arbitrary standards of decline.
When it got bad enough, people would start stuffing their savings under the mattress which caused a 'bank panic,' we call those 'depressions.' Rich people would then take the cash they'd been hoarding and start buying things for 10 cents on the dollar. The Koch brothers fortune was created that way.
