Kansas Senate Bill Substitute HB 2117 published by the conservative American Legislative Exchange Council (ALEC), supported by "The Wall Street Journal", supply-side economist Arthur Laffer, and anti-tax leader Grover Norquist. By 2017, state revenues had fallen by hundreds of millions of dollars causing spending on roads, bridges, and education to be slashed, but instead of boosting economic growth, growth in Kansas remained consistently below average. That year, the Republican Legislature of Kansas voted to roll back the cuts and after Brownback vetoed the repeal overrode his veto. As a conservative Republican Senator from Kansas, Brownback had been reelected by large margins in 1998 and 2004, and
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
