Subject: A country becomes more interesting and develops more quickly when its populations includes a mixture of nationalities. To what extent do you agree or disagree?

Along with the globalization, many countries are in the tendency of encourage the legal migration with the ultimate aim of reach the great merits. On the contrary, it is hugely argued that the mixture of nationalities could pose countless cut-throat drawbacks. My subjective viewpoint is that their advantageous aspect can compensate the disadvantages.

On the one hand, the mixture of nationalities exists some remarkable consequences. It is itself seemingly that the social evils are more interested in. With the soar of the juvenile delinquency rate, some lay the blame on the migration and require the state authorities to strengthen the law with the purpose of restrict this status quo. Furthermore, the competitiveness within the in-and-out labor market seems one of the leavens why the majority oppose the combination of nationalities.

On the other hand, in terms of the economic progress, the legal migration can gather the brainy persons so as to boost the national burgeon. The United States of America seems the eloquent example of this arguments. Thanks to the appropriate policies, after 250 years from the independence day, the USA turn a nation with dominant position on multi-aspects. Regarding the praxis values, the mixture of nationalities have great impacts on the shaping and betterment of the customs. Consequently, the unsound customs will quickly reject and the moral sound values could be widespread.

All in all, despite many drawbacks, the mixture of nationalities renders some huge benefits. All things will reach the peak of success, only if they overcome the radical balance.
