It depends on two things, which are missing from your post or question. First, a better life is relative. Some people can find a monthly salary of $5000 in DRC great and sufficient while others will see that as too small, depending on the housing cost they want and so on. Second, you dont have a job offer so its difficult to know how that would translate into your better life.
In short, its depend on your salary and lifestyle.
Good luck!
