What I learned from this article -

It costs $50,900 from 65 to 75.

It costs $206,200 to get from 55 to 75.

Therefore, It costs $155,300 to get from 55 to 65.

It costs $146,600 to get from 65 to 85.

It costs $372,400 to get from 55 to 85.

Therefore, it costs $226,200 to get from 55 to 65.

The article says it costs $119,600 to get from 55 to 65.

$226,200 != (not equal) $155,300 != $119,600

Therefore, this article is the epitome of shitty reporting.

As someone said, I assume inflation is in here somewhere, but if an article is going to write a report like this, they ought to include assumptions. I'm sick of using online calculators, then realizing they make BS assumptions.
