If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width. At this point in my career I mostly teach Calculus and Differential Equations. While there is some review of exponents, factoring and graphing it is assumed that not a lot of review will be needed to remind you how these topics work.
Overview[ edit ] U. For example, the top 0. They became moderately less progressive between and  but slightly more progressive measured between and Income transfers had a greater impact on reducing inequality than taxes from to While before-tax income inequality is subject to market factors e.
The influence of the labor movement has waned in the U. Shillerwho called rising economic inequality "the most important problem that we are facing now today" former Federal Reserve Board chairman Alan Greenspan"This is not the type of thing which a democratic society — a capitalist democratic society — can really accept without addressing" and President Barack Obama who referred to the widening income gap as the "defining challenge of our time".

Wages remained relatively high because American manufacturing lacked foreign competition, and because of strong trade unions. By more than a third of non-farm workers were union members, : This tremendously productive working class gets back for its own consumption a smaller part of its output and hands over in the form of profit to the capitalist owners of the instruments of production a greater part of its output than does either the English or the French working class.
Studies have found income grew more unequal almost continuously except during the economic recessions in —91Dot-com bubbleand sub-prime bust. Beforea larger share of top earners income came from capital interest, dividends, income from rent, capital gains. Afterincome of high-income taxpayers comes predominantly from labor: Inthe Occupy movement drew considerable attention to income inequality in the country.

Higher-income groups tend to derive relatively more of their income from more volatile sources related to capital income business income, capital gains, and dividendsas opposed to labor income wages and salaries.
Other sources of capital income also fell: CBO estimated that "average federal tax rates under law would be higher — relative to tax rates in — across the income spectrum.
The estimated rates under law would still be well below the average rates from through for the bottom four income quintiles, slightly below the average rate over that period for households in the 81st through 99th percentiles, and well above the average rate over that period for households in the top 1 percent of the income distribution.
Lindert and Jeffrey G. The share of incomes for those in the bottom half of the U. Pretax incomes for the top 0. The economists also note that the growth of inequality during the s to the s can be attributed to wage growth among top earners, but the ever-widening gap has been "a capital-driven phenomenon since the late s.
Causes of income inequality in the United States Illustrates the productivity gap i. Each dot is an industry; dots above the line have a productivity gap i. A study in the American Sociological Reviewas well as other scholarly research, using the broadest methodology, estimates that the decline of unions may account for from one-third to more than one-half of the rise of inequality among men.
As unions weakened, the vast majority of the gains from productivity were taken by senior corporate executives, major shareholders and creditors e.Steps for Solving a System of Inequalities Word Problem.
