What are the positive and negative effects on a country when emigrants leave?

This is a seventh-grade social studies question.

"Brain drain" - negative
"Exportation" of the impoverished - positive

When citizens not in reference to visa holders that decide to leave and emigrate to another country; the negative side is that the unemployment rate may increase due to the job market; that the jobs themselves may not become favourable to those that want higher salaries or better working conditions as well as chances of rising up the corporate ladder depending on the industry.

This leaves business that are advertising through online websites and news papers feeling the unnecessary need to utilise recruitment agencies to pay exuberant amounts of money to find the right candidate; even though some times this may be necessary to offset any efficiencies or delays in the work environment of the organisation.

There is a perception in some peoples' mind that local citizens do not work as hard as migrants especially when the need is required for them to bring people from another country to take up the unwanted jobs by providing better incentives that attract them to come over in the first place.

Another negative side of things is that for those who have not emigrated to another country and prefer to stay in that country; feel that they are some times ashamed or embarrassed to feel that the jobs have gone to foreigners rather than its local citizens and may create a disparity amongst the population that could increase the unemployment rate and a gap in the various industries feeling that the job market is pointless to get into because it is getting filled up by foreigners who want a chance to start a new life and are willing to start the job at a lower salary package; therefore becoming more competitive.

If the feeling for local citizens that its almost pointless, then the existing local support systems such as social security and other welfare organisations could well be more stressed and allow local citizens to heavily rely upon rather than their foreign counterparts that can not obtain government assistance due to their visa restrictions.

One could almost find some similarity with Asylum Seekers of any country; where the only difference is that they tend to come to the country illegally without documentation; and if they did; then they would tear them up and costing the country more in the process to sort them out; while at the same time provide them with economic assistance more so readily than its local citizens. However this is a separate argument of its own and its more to do with stupid and disorganised government spending.

Some citizens may also feel that there is no room to expand (may be due to population) in terms of their occupation and lifestyle that they may often feel crowded or too overwhelmed due to their own perceptions; which means going overseas where the prospects are higher for economic and social growth and may end up sacrificing various things in order to obtain a better foreseeable future.

The positive side, it brings in cultural diversity and the chance for other industries to thrive, such as tourism as well as import and export growths to supposedly improve a profitable GDP growth of the country with more productivity.

I can only see more negative aspects than positive ones to this sort of circumstance.
