If they do not want to split up family then self deport! Basically they just don't care that their parents broke the law and brought them here as children and babies. They are saying no consequences for breaking the law. I work with lots of Hispanic and they believe it is a right to be here. In fact if they could they would fill the plants with Hispanic workers and there would be no Americans. Where I work it is chain employee's. Many of them are family and friends. Its a family reunion every day.
Oh and "dreamer" means dreaming of getting rid of Americans.
Aside from the illegal/legal aspect, that is how migration and immigration have taken place since people graveled on foot.
People sailed across the Atlantic to settle. They sent letters back home, informing their families to come on over, too.
I dine at a particular Mexican fast food chain restaurant. Most of the Hispanics working there, originate from the same villages and towns, in Mexico.
In Chisago Lakes region of Minnesota, the people who started settling there, came from the same counties in Sweden, because of "letter home."
IOW chain migration is not a new conspiracy. I'll wager most of use, that have ancestry back to Europe, came to America in similar scenarios.
My own spanned 1634 England-New Hampshire, until 1871 Sweden to Minnesota and hundreds in between.
I oppose continued chain migration, other than the most narrow definition. The DACA beneficiaries can go back home to be with family.
