Economic policy of the George W. Bush administration finance Social Security and Medicare benefits as well as investments in schools, health, infrastructure, and basic research... [and] generate further inequalities in after-tax income." The Bush administration had claimed, based on the concept of the Laffer Curve, that the tax cuts actually paid for the themselves by generating enough extra revenue from additional economic growth to offset the lower taxation rates. However, income tax revenues in dollar terms did not regain their FY 2000 peak until 2006. Through the end of 2008, total federal tax revenues relative to GDP had yet to regain their 2000 peak. When asked whether the
Optimal foraging theory shown as a curve of energy gain per time spent in a patch (Figure 3). The curve starts off with a steep slope and gradually levels off as prey becomes harder to find. Another important cost to consider is the traveling time between different patches and the nesting site. An animal loses foraging time while it travels and expends energy through its locomotion. In this model, the currency being optimized is usually net energy gain per unit time. The constraints are the travel time and the shape of the curve of diminishing returns. Graphically, the currency (net energy gain per
