In the interest of learning the middle, and upper middle class's vocabulary I respectfully make the correction that you probably meant that you went from the 1st percentile, to the 98th (of income, I believe you imply). I've seen my parents make a climb in socioeconomic "position" similar to yours, and I've found that much as you found one of the fundamental things that separate the "classes" is awareness of taboos, and even more importantly, when taboos can be violated! My observations seem to indicate that the level of "taboo observance" is distributed in a bell curve over the incomes.
