Even if you're right that dreamers "should be upset with their parents," does that mean they should be punished for their status, over which they had no control?  It seems to me common sense should dictate that something can be done for them.  After all, to qualify for daca, dreamers had to meet certain conditions, including nearly spotless criminal records.  Financially, they provide quite a bit of tax revenue.  An analysis found that ending daca would cost the u.s. government more than $460 billion in lost gdp over the next decade, along with a fiscal cost of over $60 billion to deport the approximately 800,000 dreamers.  In addition, it would cost employers "$3.4 billion in unnecessary turnover costs, while cutting $24.6 billion in medicare and social security contributions over a decade."  Does any of that make any kind of fiscal common sense?  

Personally, I would prefer to keep the dreamers and get rid of the white supremacists and neo-nazis.
