I had heard about "Gadsby" first, so when high school friends told me they were reading "The Great Gatsby", I was quite confused about why their English class would assign a book most known for not using the letter 'e'.
Sure, money managers have a significant interest in lying about their likelihood of outperforming market averages (6.6% real return in the last 100 years, by the way, not 5%), but their fees don't mean that "compound interest is a lie."
Compound interest isn't magic, it's just pretty simple math.
There are a lot more options that I can take into account using the NYT version (ownership costs, HOA fees, specific mortgage rate, length of mortgage, rate of return of other investments, etc). How is this calculator better? Just because it’s simpler?
Response from Groupon:
“Mr. Nels[e]n initially approached Groupon and our merchant advisors structured a deal to best encourage overspend and help his business grow. We also required Back Alley to cap the number of Groupons sold to ensure the feature was in the best interest of both consumers and the merchant. We scheduled his feature on his terms, on a date he selected, under a contract he reviewed and signed. According to our records, only 132 Groupons, or 18% sold, have been redeemed since Back Alley ran two months ago, and Mr. Nels[e]n has received 2/3 of his share of the revenue to date. We always hate to hear that a local business has decided to close, but the math does not point to Groupon as the cause.”
