What do you even do abroad?

Most of the people in this country want to go abroad after their hsc or ssc. And i do understand the lack of opportunities and the deteriorating state of the country, but after getting out - what do you even do there besides studying? It already takes a lot of money to get there and then you have to manage your finances there but at the end of the course, you have spent a lot of money that god knows when you're gonna recover unless of course you have a good scholarship but for the average kashem who wants to go abroad and become rich without any skill or anything -- HOW? Whats the game plan after that?
