Profits accumulate to asset holders, and individuals have a fundamental cap on how much they can rationally spend. If individual asset holders have too much capital - then there won't be enough spending to keep the economy moving, resulting in deflation. Even in the case that large asset holders are efficiently lending capital, this situation can occur due to interest payments. The US Government effectively acts as the borrower of last resort in this situation by being the only place where a large asset holder can safely store capital and spending the borrowed capital. It would be possible to perform the same activity with taxation, or policy decisions that raise the base wage in the economy, or by simply printing more money - but the activity must be done to prevent deflationary spirals from occurring. Printing money comes with the con that asset holders will end up with more capital. Unfortunately, there is no guarantee that such holders remain obligatory savers, and they may begin engaging in irrational spending.
