Tracking personal finance doesn't have to be terribly difficult. A simple spreadsheet with expenses and income often suffices. Maybe some simple divisions so that you know that x % of the paycheck will pay the mortgage and y % will be used for the insurance. Nothing too fancy or time consuming. Just enough to reveal patterns, and make sure you have enough "flex" in your bank account for things like personal emergencies.
Although I know you are saying your advice is for the upwardly mobile only, my impression is that a lot of people are very bad with their finances -- that includes even some of the "upwardly mobile". Maybe you're good with your personal finance and have no need to track, but I personally think the general rule should be that most people should do some rudimentary tracking.
I was speaking specifically for that audience and not for the broader one. Of course my way of dealing with money only works for people like me. I refer specifically to the "upwardly mobile", which is generally taken to mean those who make more than the average and are still capable of climbing the social ladder.
When you are climbing the social ladder, you develop skills that make you more useful to people. When you learn accounting, you are learning a skill that will keep you from shooting yourself in the foot financially. It will not make you much more useful to others except in that regard. Sure you can get a job accounting, or use it to help run a business, but the benefits are too limited to justify doing it yourself. Hire somebody and use the time saved to learn something more useful.
I never intended to say that people should not have a handle on their spending. Accounting / budgeting is one mindset that will give you such a handle but not the only one.
