One big measure of a stable economy is income / job generation in all spectrums of society.
When there’s stability within the country, investors flock in and make long term business plans. They are encouraged and motivated to put in their money because they are confident that there are opportunities to earn. Companies are more optimistic and aggressive in their expansion programs. This happens when government is perceived to be competent, able, trustworthy, credible, dignified. Businesses will flourish when there’s stability which includes peace and order in the streets. Businessmen can go about their daily operations without fear of danger to their property and person. Stability in a country spurs growth and progress, creates jobs, generates income for the citizens and its government.
