Half of the society believes that moving to a new country could lead to having a better life, whereas the other half rather stay in their native place. This argument depends on which area you are moving to because if is not as developed as the zone they came from the disadvantages could exceed the advantages. From my own perspective, staying at home can make you happier in general.
On the one hand, making the decision to emigrate is hard as you may leave all you know to go to a new place where probably do not have anyone to rely on; moreover, language can be a great barrier to face too. For instance, students who finish their degree at college and want to start working are looking for the best employment they can find and earn as much money as they can so moving from Spain to Canada, even the second is more developed than the first, could be a great option; nevertheless, there are some aspects, like weather, that cannot be provided by this new city. Canada could have better incomes and opportunities but the reality is that a lot of papers have to be done in order to be able to move in. In my opinion, the job offer should be extremely tentative to do it.
On the other hand, remaining in your home could be the easiest option, as having contacts could lead to work opportunities that may satisfy expectations, however, the salary may not be as high as in other places. For example, nowadays in Spain, the minimum wage is not enough to be able to live a luxurious life, notwithstanding the majority of the Spaniards decide to stay in their country because the Spanish lifestyle cannot be found anywhere else. The way I see it is that not moving abroad can also have many advantages as having family closer and being able to enjoy the area you have been raised in.
To summarize, starting a new life is challenging but in some cases could be worth it, on the contrary, deciding not to could be a great option. From my point of view, there is no place like home.
