Cynicism: Is one usage-sense close to pessimism? [closed]
Solution 1:
The fundamental meaning of "cynicism" is "the belief that people are only motivated by self interest".
For a cynic, it therefore follows that "if some plan or idea is not motivated by self interest, then it will not be carried out".
Your sentence "the recent economic and security situation has made me cynical about this country's future" is fine. It means "I think the future of this country would be better if its leaders did not act in their own self interest, but I don't believe that will happen."
