Colleges and universities are fond of reminding anyone who will listen that there is great value in earning a bachelor's degree. In the most recent statistics available the U. S. Census Bureau tends to agree.

Results from the 2004 Census Bureau report shows a $23,000 difference between the average annual salary of adults with a bachelor's degree ($51,554) compared to adults with a high school diploma ($28,645).

In what may or may not be an anomaly, the income gap narrowed slightly from five years earlier when bachelor's degree graduates made nearly twice as much as high school graduates.

The percentage of Americans 25 and older with a bachelor's degree rose to 28%, and the percentage with a high school diploma rose to 85%. In 1970, 36 years ago, only 11% of Americans had a bachelor's degree and a little more than half had a high school diploma.

It is probable that the increase over time has had much to do with the advent of technology in our society, and the impact of Internet accessibility to the general public in 1993 and 1994 through the creation of browsers.

If you are wondering, Minnesota, Utah, Montana, New Hampshire, Alaska and Washington had the highest proportions of adults with at least a high school diploma, all at about 92%. Texas had the lowest with about 78%.

Connecticut had the highest proportion of adults with a bachelor's degree (37%) and West Virginia had the lowest (15%).

I have long been a believer that there is no real correlation between education and income unless the degree leads to a high paying profession, such as a physician, attorney or dentist. I have known too many people with bachelor's degrees working at McDonald's restaurants.

My standard comment is that it is not like all people with bachelor's degrees make $100,000 a year and those with high school diplomas make $30,000. I also have known many people with only high school degrees and some high school dropouts who make well in excess of $100,000 annually, especially in sales.

Bill Gates is a college dropout who ranks as the richest man in the world. Forbes magazine rates William H. Gates III as the richest person in 2006 with $53 billion, proving perhaps that even Harvard dropouts can make a lot of money.

You, dear reader, will have to decide for yourself how big a difference in income is possible with a college degree instead of settling for a high school diploma. There is no question in my mind that the income gap will increase as the upper and lower edges of our middle class are falling away and the gap between the rich and poor in America widens.

I also have found little correlation between talent and income, intelligence and income and experience and income. Is there anyone in America who has not heard of the starving artist, or educated idiots in menial jobs, or janitors becoming millionaires?

The only real correlation I have noticed is between people skills and income. How else can you reasonably explain how a high school dropout becomes a self-made, multi-millionaire entrepreneur?

These successful entrepreneurs may not have perfect subject-verb agreement when they speak, but they certainly know how to relate to people in a meaningful way. You may have noticed that the whole world steps aside for the man who knows where he is going (ditto for women).

Also of note is the Bureau of Labor Statistics National Compensation Survey which shows that white-collar earnings average $21.85 an hour while blue-collar earnings average $15.03 and service occupations average $10.40.
