Couldn't find it, but then how the hell is it a round number?
Because they just indexed it so it wont stop being a round number until next year.
You are not making incremental changes for the better. You are cementing a status-quo.
Every good change ever has come from incrementalism. Abolition, suffrage, civil rights, progressive taxation, social security, medicare, medicaid, S-CHIP. Every one of these was watered down in the first draft and improved later on. And currently we are in the middle of Obamacare which was watered down at first but which can be improved right now. And this clinton tax credit is an example of "improved later on". You just keep making additions and fixes and eventually you fix the problem.
Hell Bernie Sanders was calling for a "revolution" and he was still talking about incremental changes.
