In the next several years, regretably each of my siblings will receive several hundred thousand dollars from my parents estate which is all invested in cash or cd’s (no more than 100K in any bank). The money couldnt be more secure and there is so much insurance that it would be impossible to spend the assets down. My parents were very middle income folks but children of the depression. They saved everything and lived humbly as I do. I know many other people just like them. There is a HUGE wealth transfer coming to the boomers in the next decade. Whereas our parents were savers, we tend to be spenders and this money will hit the economy in a big way. This is one source that will have a substantial impact on a macro level. I’m sure there are others.
