Arthur Laffer that U.S. tax rates had in fact reached such extreme levels." Laffer is currently an economic adviser to Kansas Governor Sam Brownback, who in 2012 zeroed out state tax liability for approximately 330,000 of the top wage earners in the state. The state, which had previously had a budget surplus, experienced a budget deficit of about $200 million in 2012. Drastic cuts to state funding for education and infrastructure have been implemented because of the budget deficits. Brownback's tax overhaul was described in a June 2017 article in "The Atlantic" as the United States' "most aggressive experiment in conservative economic
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
