Insight by History

More democratic systems tend to have lower average tax rates because broad citizen participation and many low- or non-taxpaying voters reduce average burdens, whereas autocrats can impose higher effective takes on productive citizens.

Firms cluster together because proximity lowers coordination friction with suppliers, competitors, and complementary firms, which makes collaboration and operations faster, cheaper, and more efficient.

Spending public resources on citizens weakens a ruler's hold because each unit spent on public goods is one less available to buy loyalty, enabling rivals to lure away supporters by promising the same benefits.

Some devices use grid frequency as a time reference, so frequency stability is critical because counting AC oscillations requires a consistent nominal frequency and deviations cause timing errors.

Democratic leaders invest in public goods because raising citizens' productivity expands the tax base, so even with lower tax rates the absolute resources available to reward supporters and fund government increase.

Improved transportation expanded how far people can reasonably live from markets because faster travel increases the distance reachable in a given time, making settlement farther from marketplaces practical and fueling suburbanization.

Corruption often functions as a deliberate tool of power because leaders use legal loopholes, favorable contracts, and tailored laws to transfer benefits to influential supporters in exchange for loyalty, institutionalizing favoritism rather than relying on overt bribery.

Transmission voltages are stepped up at power plants because higher voltage carries the same power with lower current, which reduces resistive (I²R) losses over long lines.
