Egg yolks are indeed full of cholesterol. Like most cholesterol-rich foods, they are jam-packed full of important nutrients, especially the fat-soluble vitamins and essential fatty acids. In fact, the slew of nutrients in an egg yolk is so comprehensive that a few a day would offer better insurance than a multi-vitamin.
In the United States, approximately 7% of households are millionaires.[7] A 2010 study argues that millionaires (those in the top 1% of earners) pay approximately 40% of all taxes in the United States.[4] According to the book The Millionaire Next Door, only 20% of millionaires inherited their wealth.
Still, millionaires are on the rise each year. The report includes growth in other wealth segments, up to and including investors with a net worth over $25 million. The number of millionaires increased at a greater rate than the number of super millionaires. The number of $25 million-plus households grew by 3,000 to 145,000. According to Spectrem, 9 percent of all American households have a net worth of more than $1 million, which is up from 5.9 percent in 2008. There will always be people who have an easier time socking away money, because they live off of substantial wages.
