Why did Rome defeat Carthage?

1) Carthage spent most of its income on the maintenance of a mercenary army. The mercenaries fought not for the independence of the Carthaginians, but for money.
2) Rome opened up access to citizenship rights for subordinate communities, giving them the benefit of their gains. Rome did not impose constant levies on them.
3) In Carthage, monetary economy prevailed over agriculture, and in Rome, on the contrary.
4) The Romans united with the Greeks. In a short time, they taught simple garazans to maritime business and built new large ships.
5) The Carthaginians were traders, not experts in war. The inability of the Carthaginians to create a strong state.
6) Rebellion of the Carthaginian mercenaries. The betrayal of their homeland by the Carthaginian commanders.
7) Skillful strategy and wait-and-see tactics of the Roman military leaders. The enrichment of Rome through taxes from the conquered provinces and the support of the African population.
