It is a simple piety to say that America was built by immigrants. The United States, both wealthy and capacious, has in recent decades been a primary destination for Latin American immigration, and with good cause; with homes racked by poverty and political instability, people wanting a future sallied north. They took their children with them, came here, and made lives for themselves. The children, still formally undocumented, grew up and made their own lives. There are numerous reasons to oppose ending DACA, and I stand with a myriad of other leaders in the technology sector in condemning the revocation of a policy designed merely to protect those who have spent their entire lives as productive, law-abiding Americans.
