The battle is on, and nothing less than the soul of America is at stake.

The truth is that relative income is not directly related to happiness. Nonpartisan social-survey data clearly show that the big driver of happiness is earned success: a person's belief that he has created value in his life or the life of others.

Whether we look at capitalism, taxes, business, or government, the data show a clear and consistent pattern: 70 percent of Americans support the free enterprise system and are unsupportive of big government.

The more control you have over your life, the more responsible you feel for your own success - or failure.

The key to happiness is not being rich; it's doing something arduous and creating something of value and then being able to reflect on the fruits of your labor.
