Yep. The 1978 BMW 320i was $9300 msrp and $7500 avg retail cost.
Same model car today 40 years later is $42,000.
That’s a 40 year look at inflationary pressures in a snapshot.
A 30k a year public university would be 120k per year or 480k for four years, roughly a quadrupling of cost in fourth years. Divide by two for the 20 year mark. Sure 240k isn’t outside of the realm of possibility at all.
Hopefully inflation levels stay low but then we will also see anemic wage growth which won’t be palatable to most Americans. Bit of a problem.
