Why do i say so , well the govt is in charge of policing which affects the economy generally and translates into either well paying jobs meeting minimum wages and also helps in setting the tone of employment , the govts involvement also helps bring down inflation which helps fix price of goods and service's which trickle down to the citizenry and the ability to afford them or not.
Btw i dont know about other countries but the government is the biggest employer in most countries and if its not employing it means more people will be out in the street's jobless trying to survive if poverty doesnt get to them first but in this modern technology its important to equip ourselves with extra skills to survive.
There are many thoughts on this one. Considering the population, the literacy rate in the country, infrastructure, and people's voting towards good government can make big difference. If a country is hosting a government body which has very poor co-ordinated people then definitely they won't good for the country. Poverty is not the definition of money actually, it's all about how literate people are. If the literacy rate increases then definitely employment changes, people start earning money as per their skills and increase their wagers over the period of time.
So if any country promotes education at its best then they will develop. The government will also receive a handsome amount of revenue in return considering 99% of people are working class. Thus, they can focus on other stuff like national infra, more educational institutes, higher research, and much more.
