Even the poorest Americans and members of the developed world have more conveniences and luxury than royalty of the past! If you have a television, a car, or electricity, you are living better than a KING? 78% of those earning between $25,000 and $50,000 were somewhat or very happy. In other words, over 3 out of 4 people in that income level were happy! Now, bump up the income levels a bit; there is only a 3% difference in happiness between those making $50,000-$75,000 and those making $75,000-$100,000!
