All countries still use electoral systems where people are elected to represent the causes and views. And parties to organise those people and views.
It’s ineffective and prone to corruption and subjectivity of representatives and money interests beginning with influence on elections. Solving of any issue can be delayed indefinitely if representatives don’t feel like it’s urgent.
In computer age it’s long overdue to have a modern system with people directly voting for issues and causes and not represented by any middlemen.
