People have always migrated, but modern mass migration is a result of the economic extraction & resulting instability being so extreme that someone with minimal opportunities in Spain can make more money than your average person in a colonized country.
It’s not uncommon for migrants going from having middle class jobs (teachers, small business owners, etc) to cleaners and still having money to send home to support their family.
Additionally many people will migrate to Spain, England & France because their language is widely used in colonized nations.


Morocco was colonized by Spain, as were several other places in Africa, hell the Conquest of the Canary Islands was the first instance of European genocidal settler colonialism in Africa.
