"Only" $13 billion more is still an increase.
So what's the danger for you in admitting that the tax cut reduced revenues in FY 2018? Simply put, if you admit that the tax cuts didn't increase revenues, that means that consumer spending didn't increase by way of "letting people keep more of what they earn", ostensibly to spend in the consumer market, which increases economic activity and thus, increases revenues.
By showing that revenues
declined in FY 2018 once the Russia Tax Cut you love started, it invalidates the premise you have that revenue "sometimes" increases following a tax cut.
But more importantly, it gets to the heart of the way you conduct yourself on these boards; posturing a BoTh SiDeS narrative to position yourself as some sort of moral arbiter because of a cold (but ultimately inaccurate, sophist, and vague) analysis of the facts. A cold analysis of the facts,
if you had put in any effort into your argument, would have revealed that revenue declined following the tax cut in FY 2018. That while overall revenue growth was a measly $13B, that was solely thanks to the pre-tax cut revenues that came in the three months prior to the start of the Russia Tax Cut. A sober, analytical approach to the data would have revealed that almost instantly; but you didn't approach the data soberly or analytically...you approached it emotionally and selfishly, thinking you could slide a half-assed argument on through without proper due diligence.
How'd that work out for you? Not great.
So now you're reduced to pretending that the NET revenue increase is a consequence of the tax cut, while deliberately ignoring the data showing the tax cut is the reason why revenue growth was so low to begin with, and that revenue growth for FY 2018 is thanks to the non-tax cut months of Oct-Dec 2017.
Of course 2019 revenues would be higher than 2018; there was no tax cut that went into effect this year.
If you had a student who submitted a paper to you that presented a false conclusion that wasn't supported by a deep dive into the data, and who ignored your criticism of their inaccuracy, sophistry, and lack of detail, would you pass that person in your class?
