Government agencies protect their institutional interests because departments derive jobs, funding, and authority from administering specific laws, so they resist data or policies that would shrink those programs and the careers tied to them.

Potential supporters weigh expected survival and rewards before backing a coup because in stable democracies many already enjoy wealth and protections, and the risk of being purged after a seizure often outweighs uncertain gains.

Businesses locate in cities to access the best labor pool because workers cluster where jobs exist, so firms seeking top talent must be where people are, which in turn draws more businesses into the same places.

Middling regimes are most prone to revolution because they must extract enough from citizens to reward keys while still leaving citizens capable of revolt, creating a higher risk of upheaval than very rich autocracies or strong democracies.

Some industries locate outside cities because high urban land costs can outweigh the benefits of proximity, so space‑intensive or low‑margin operations move to cheaper locations to cut costs.

When popular revolts succeed in middling dictatorships, regime change is often driven by elites because uprisings only prevail if the military or powerful courtiers withdraw support, and those elites then replace the ruler to protect their own positions rather than enact mass reforms.

AC is used across the grid primarily because its alternating polarity lets transformers change voltage levels, enabling step‑up for efficient long‑distance transmission and step‑down for safe local use.

A democracy becomes vulnerable to seizure when it grows very poor or a huge resource is discovered because the expected rewards from controlling the state spike, changing backers' calculations and making a small organized group's gamble more attractive.
