"I'm sure, Joseph, that economic/capitalist/money immigration/emigration is not a good think for several reasons."

Another unjustified comment, with no proof. Is it not a good thing for the individual, the area the individual has left or the area the individual has gone to? What are the pros and cons resulting from emigration for each of these? Balance these up, ideally with lots of supporting evidence and examples, then you can say whether it is a bad or good thing, then you can hold a justified opinion.

What is good anyway? Good for culture, the economy, happiness, infrastructure, environment? Its no black and white issue (or maybe it is :-p )
