We've confirmed the code is working on several other browsers, both desktop and mobile versions, so the issue right now looks specific to Safari and potentially mobile Safari. The last time we confirmed the tool works in Safari was 2018, so that would narrow the potential issue down to changes in Safari since then.

I suspect the code's vintage may be an issue. It was originally developed in 2006 to very specifically be backward compatible with older versions of JavaScript, where I can see Apple perhaps phasing out supporting some of the coding aspects that have become obsolete.

We do have another tool that uses the same data and many of the same formulas, but with a more modern implementation of code (http://politicalcalculations.blogspot.com/2009/06/investing-...). If you run into the same issue, that would suggest other changes in Safari are at work.

Yes and no. The ASEC survey is capturing total money income, which is not the same as total compensation. It's an important difference, because total compensation includes things like the value of employer-provided health insurance that has never been included in the total money income measure.

Also keep in mind that a lot of that intense technological development has resulted in falling costs for a wide variety of goods over time.

One of the bigger questions that society needs to answer is why the costs of the things that have been rising so much faster than incomes are doing so.

Here's the update for August 2018:
