that's a very crappy rate
first I don't believe the government numbers, lying is the life of a politician, that is what they eat and breath, so the CPI number is bullshit, so let's assume the CPI rate at, at least 8% per year
the video says when she died she was 100 years old
so she bought that shit when she was 25
if her crap were making her 15% per year then they were actually making her 7% per year after inflation
if she wanted to sell those shitty shares when she was a fucking fag hag at the age of 50, she would get $5925, even though she had invested $1092 (in terms of USD at her age of 50)
180 x 1.15<sup>25</sup> = 180 x 32.92 = 5925
5925 / (1.07<sup>25</sup>) = 1092
fuck that shit, that's shitty news, she didn't even have any kids, the university benefited from her pathetic existence
