When I started full-time work in 1980 after grad school, the inflation was so bad my megacorp was giving raises every 6 months instead of yearly. There was talk of existing engineers making the same or not much more than new hires, and the corp had to give everyone raises. They had to, in order to retain employees.
That was the effect of 15% inflation. The 30-year mortgage rate was 14% when I bought my home in 1980, and I do not remember if that included the 1/2% mortgage insurance. A year later, the mortgage rate reached 18.63%, according to Federal Reserve data.
Between 1978 and 1981, I was a Plant Manager of a large manufacturing company in Connecticut. I recall giving out 15% to 20% annual pay raises to my supervisors during that time.
In late 1981 I was promoted and relocated to California where I faced the high housing prices. They were double + of what my home in Southbury, CT was valued at. The Company made it worth my while to relocate with monetary benefits on the sale of my current house and the replacement house purchase. None the less, having a new 18% mortgage in Ca was daunting at that time.
What we see now is a Fed-induced recovering economy through the showering of money to prop up the banking system (which CANNOT fail in this economy), and the effects of Covid shutdowns (shortages, etc). The Fed has backed themselves into a corner since the Great Financial Crisis and "QE forever" may be the status quo. Remember when Bernanke said the QE was ending?
It is my feeling that interest rates will have to be increased at some point in the future to slow down the Fed-induced spending and recovery that is keeping the new inflation monster fed. I have no GUESS as to what that will mean for the equity market when that happens, but if interest rates get high enough, I will be feeding on CD's.
DW and I are on the dark side of 70's age group (I'm close to 78, she's 76), and we have careful with our retirement funds that remain. Having the house paid for is a blessing and our lifestyle is one with minimal needs. So we will be OK. We are more worried about health issues at our ages as we are seeing friends and family members passing away on a frequent basis.
On this last Easter Sunday, my SIL's husband, who was my best friend for nearly 30 years, passed away from kidney failure in a Sacramento Ca hospital. We spoke by phone two days prior to his passing and he said he wished he and I could play golf together again like the many times we did in the past. Not once during our hour long call did he mention the millions of dollars he had in his retirement accounts or what he wanted to do with his good fortune.
