>People buying the bare minimum also means there's little investment going on, which needless to say is bad for economic growth.
Growth for who? There is little investment going on, that is the point, ventures that cant profit die, freeing their resources up for more productive ventures.
>Why would that be the case?
In this paragraph you moreso identify the market forces that eventually cause rates to come down. Eventually there is enough savings, and when companies come forward demonstrating their ability to create value, competition between savers pushes rates back down. This comes after the period of everyone stuffing their money under the mattresses.
You are confusing saving and lending, there is a creditor (buyer) for every lender, not every saver.

Lets summarize. I hope you find the following to at least engage you and make you question your prior understanding of the issue at hand.
You are concerned that companies will own everything, but are not concerned with the 7% YOY (its not 2-3%) growth in the money supply, and how all interest on money that was printed into existence. The principle of that money will eventually be taken back out of circulation, leaving interest that remains to be paid. If you bought a house, but only paid back the principle, the bank is still going to repo your house, they own it afterall; there isnt enough money in the economy to repay the principle, meaning either mega-default across basically all industries, or we have to take on more debt to repay the interest on the last debt; since we are dealing with precentages and compounding interest, a greater and greater sum of resources go explicity to repaying debt.
If you wanted your repo-men world where everyone is enslaved to debt and private companies, thats all you need, just let it play itself out. If you really wanted to take it up a notch though, theres more we could do to confuse and repress the poor. Print lots of money, it doesnt matter how you justify it, forever wars, bank bailouts, socialized healthcare and welfare, it doesnt matter! When this money is printed, it will accelerate the process by rapidly growing the total amount of interest owed, and you will of course have your pockets open to receiving these streams of cash.
Why do you think politicians have been getting so rich off the stock market? Do you think its because these people are world class investors? All of them? They are invested in the same companies that they regulate, and by that I mean they protect those companys against competition, and provide stimulus when possible.
For the average person? The time-price of everything this money touches goes up, thats how many hours the median american has to work to aquire a good. Housing, healthcare, education, defense, everything that is paid for with money being printed into existence, is going up in price dramatically. Things like, tvs, computers, they become more accessible every year.
