Worth Does Not Equal Wealth

Warren Buffet often says he happens to be very good at something that is very financially rewarding – effectively allocating capital. He says this while making the point that plenty of other people are exceptionally gifted in ways that are not as financially rewarding (teachers, grandparents, nurses, Peace Corps assignment…) but are important to society. He understands that his worth as a person is not tied to this bank account. It might be one reason he and Bill Gates have so generously used their wealth to help others. They understand those actions are related to the their worth.

People should not tie their feeling of their own worth to their income. We don’t talk about it much directly but I see it far too often in the way we discuss things. Most people agree we shouldn’t judge people by their bank account or their earning power but we still do it. Hey we have flaws. We also judge people based on how attractive they are and how tall they are and other far from sensible things. Study after study shows we do this even if we want to pretend we don’t.

At least in the USA far too often people mistake financial success for worthiness. Financial success is great (I am not one of those that sees wealth as a bad thing – even if the correlation to bad behavior can seem high, at times). Even in companies this is often done where those with higher salaries are seen as more worthy – not everywhere, not all the time, but still more than we should. And when the economy is bad more and more people face not only financial struggles but the added pressure of feeling less worthy as they struggle financially.

I think it is good that we feel a desire to contribute and play our part in making our communities successful. But we shouldn’t be overly critical when we are making real efforts to contribute but for example, the job market is very bad and we can’t be as financially successful as we were before. Or feel we have to judge our success versus our siblings, friends, childhood friends, co-workers, children… based on our material wealth.

Warren Buffett quotes:

“I happen to have a talent for allocating capital. But my ability to use that talent is completely dependent on the society I was born into. If I’d been born into a tribe of hunters, this talent of mine would be pretty worthless. I can’t run very fast. I’m not particularly strong. I’d probably end up as some wild animal’s dinner.” – quoted in The Audacity of Hope, page 191.

Nice Non-techinical Control Chart Webcast

This very brief introduction to control charts by PQ Systems provides a very watchable non-technical overview. Getting people to understand variation is important, and not easy. This video is one more quick reminder for those still trying to incorporate an understanding of variation into their view of the world.

The idea is simple. But actually thinking with an understanding of variation people find difficult, it seems to me. It is very easy to continue to revert to special cause thinking (who did it? is often a sign of special cause thinking) – thinking that results are due to a special (unique) cause, instead of as the result of a system (which includes lots of common causes).

The value I see in this video is as a reminder for all those trying to operate with an understanding of variation. It is also a decent introduction, but much, much more would be needed to get people to understand why this matters and what is needed.

Red Bead Experiment Webcast

Dr. Deming used the red bead experiment to present a view into management practices and his management philosophy. The experiment provides insight into all four aspects of Dr. Deming’s management system: understanding variation, understanding psychology, systems thinking and the theory of knowledge.

Red Bead Experiment by Steve Prevette

Various techniques are used to ensure a quality (no red bead) product. There are quality control inspectors, feedback to the workers, merit pay for superior performance, performance appraisals, procedure compliance, posters and quality programs. The foreman, quality control, and the workers all put forth their best efforts to produce a quality product. The experiment allows the demonstration of the effectiveness (or ineffectiveness) of the various methods.
