Bad government causes more deterioration than progress in the country. Bad government always tries to act according to its own interests. Due to bad government, the general public of the country also becomes worse. After being elected, all governments seek their own benefits.
So what would be the alternative if we assume all governments seek for their own interests after being elected, though?
I am not very fond of anarchy, even when we talk about decentralization and having one's own authority over one's good, there are always clear rules on what can and cannot happen within a decentralized system.
That is why truly good governments who keep separation of power as a priority for their way of functioning succeed to bring peace and good standards of living to their citizens and residents. Autocracy and centralization always convenient when those in power seek to enrich themselves.
