When the economy of a country is bad it causes many instabilities and various vices to the country's economy, and her citizens. In most cases, the government is in most cases responsible for a bad economy because it is their own wrong policies, and corruption in the path of the leaders that always lead to economic instability.
When a country is economically weak they cannot create all the facilities they want very quickly. Even for citizens everything may not be fruitful. Because that country has to spend a lot of money on imports. For which there is no economic growth, many problems do not become solved. Not denying this aspect, the government is not responsible for the economic weakness of any state.
Sometimes the corrupt leaders enrich themselves, and do things to the detriment of the country, sometimes they borrow money in behalf of the country, but uses such fund for their own personal business or project outside their own country.
A corrupt leadership don't care about the welfare of the citizens, they cause inflation, unemployment on the increase, high crime rate, and in some cases they contribute to these kind of mayhem directly or indirectly.
But if the defenders of a state become devourers. Then it becomes very difficult for that country to improve economically. But I think, the possibility of bringing back the solvency of such a state is very less. And gradually the balance of that state started to lose. By this the poverty rate of that state will increase day by day and the employment opportunities of the youth will decrease and the unemployment rate will increase.
In my opinion, those countries whose government is not disciplined enough, they will never work for the betterment of the citizens. So these problems will continue during the tenure of that government.
