Well what the authors have done is look to sensationalize the IRS tax code which applies to all citizens and I guess what are now called dreamers, by looking how the wealthy can potentially file. From a perusal of the writings of Emily Badger, the first author listed, she's a long time advocate for those less fortunate - the poor if you will. However, IMO, looking to demonize the wealthy is an unfortunate, albeit common way to do so. For example, in one of her writings she took issue with a service in California called LYFT. This is a service that provides transportation for those willing to spend considerably more than taking mass transit. Her position was that by people no longer paying money to take mass transit, this decreases transit's income. Might as well rail against cabs, walking, or riding a bike to work.
