The field of tech is good actually because of the rate of the need for country's development and so there will also be the need to higher personal from that area more than those in the field of PR because you only require few of such PR people but alot of tech people will be needed. The point is to look inward to see the courses that are needed in the society because those are the ones that will be in higher demand. Demand and supply are also factors to consider, if a country is tech inclined then they want more of tech hands to help them achieve that drive. However, no course is irrelevant but the demand is what matters. This is why those going to other countries for job purposes should identify the kind of jobs required in those places to know if they are well needed to avoid being stranded without job.
Right, but despite the fact that demand matters, do what you have interest in. I understand that money can be a good motive to switch and do something else but a job you’re always happy to do with a small paycheck is better than one you’re not happy to do but has a big paycheck.
