Migration and objective change

Migration brings ideology, culture and skills and practices that there are various forms of remittances ranging from social, economic to cultural and political remittances. However, I am not sure, how it brings changes in the subjective experience of the people involved but it brings changes at least in economic and objective sense. And I do not agree that it dilutes the migrating community. I think it should be seen under the framework of globalization where time and space matters. There is nothing static in this world so there is no any society which would be diluted by migration. Migration brings changes but it depends upon response and resilience of the local people. So I think, there is no dilution but it is the change that has been taking place by migration. And change always comes through the friction/fusion of ideas; contestation of ideas gives rise to the emergence of 'new' knowledge which of course not a pollution or dilution.
I would be happy to discuss more on the issues of migration, labour migration, left-behind and their livelihood and wellbeing.
