WTF happened in 1971?

The Nixon shock... Didn't work out, did it?
Dollar lost 4.3% of its value each year since then.
Multiply each number by 10 and you have todays price( minus Harvard but who wants to pay 70,000/year to get brain washed)
(1-Annual Inflation)^52years=0.1
Log (1-Annual Inflation)^52years = log 0.1
Set (AI=1-Annual Inflation)
52*Log(AI)=-1
Log(AI) =-0.0192
AI=10^-.0192=0.957
1-AI=annual inflation = about 4.3%
YOUR DOLLAR LOOSES 4.3% per year every year
Understand that!
final debasement from gold?
