I think CBT is an unfair tax system that only American's are subject to, but won't go into further detail with my personal views on this issue since some on this forum have criticized me for doing so in the past - also there are organizations actively working towards this end that appear on online search. I just wanted to post cautiously promising recent progress though.
Despite being a recent expat who has not yet had to file my first US tax return under that status, ever since I learnt about CBT, I've in the past year, upon the open call from some expat organizations, written letters to lawmakers on both sides of the aisle. I received no responses/acknowledgements from them at that time, which is why I felt this development, whether or not an "opinion paper" carries much weight, is a significant first step in the right direction by the Republicans. It's encouraging that at least one political party, regardless of any additional motives they may have, is (somewhat) supporting our problems. In particular it accepts that FATCA is not the problem, CBT is, and recommends a move towards RBT. This is only the tip of the CBT iceberg, but perhaps it does help when we make ourselves heard:

On page 293 of the pdf from download link on top right: “The United States needs to rethink its taxing rules for nonresident U.S. citizens. If a U.S. citizen is living and working abroad with some permanence, and the primary nexus the individual has to the United States is citizenship, we think it makes sense to tax the individual, as a general rule, only on income from U.S. sources.”
