I'm not impacted directly by the changes but I certainly don't like paying more taxes so I can understand why those affected are upset by the proposals. If they are misguided, however, one would expect good counter-arguments to come forward. I've read a number of articles on this by tax accountants and others, including the Comments on the articles, but so far I haven't read a single one that is convincing. Mostly it is just emotional outrage and threats to leave the country (the U.S. Treasury doesn't like to collect as much tax as possible?) if the loopholes are removed. Rather the government seems to have it right and these changes are concerned with making the system more logical and fairer. 
Sprinkling income seems particularly outrageous while the passive income aspect seems more ambiguous and one hopes that the government gets it right, namely, only eliminating abuses.   Some Comments reference other ways in which the tax system is unfair and these should be addressed as well.
