Also, consumer goods.
The voting and multiple-branches-checks-and-balances elements are sidelines.
Currently none of those promises are true in the US. The government is murdering and jailing people for whimsical and self-indulgent reasons, the consumer economy is about to crash, and the only checks-and-balances are the checks going straight to the Emperor's private accounts.
