Appreciate the researched response, but I can't follow your logic. I'm saying giving a massive tax break is a mistake because you're decreasing government revenue. I totally agree with the burdens of healthcare and social security in lieu of the aging boomers. So if anything the government is going to be absolutely desperate for MORE tax revenues.
I think you're arguing about the multiplier effect - that each dollar given back into the economy will generate far more than that. While that's true, that's for the whole economy, I'd have to see some pretty serious maths to understand how giving massive tax breaks is going to 'pay for itself' in terms of future tax revenue. Especially as the office literally in charge of evaluating the plan (CBO) couldn't stop screaming to the rooftops how bad an idea it was. And once you've done this - particularly the corporate rate drop - you can't do it again. So when the country is in recession, you no longer have that lever to pull. Pretty much the worst time to do this was while the economy had been growing so well for so long.
Further, the great champion of this brilliant, freemarketering is none other than good old Paul Ryan. Who - given the great success of this tax plan - will of course be continuing his rise in November, with none stop cheering from supporters about the tax break. Oh what's that? He's f*cking off to work as a lobbyist for one of those who got the most out of the tax plan? Oh and the GOP have so far basically not mentioned the tax plans once in their campaigning in subsequent elections - because it's historically unpopular with their own voters? Hrm...
Finally, I genuinely used to buy some of this when I was younger. Went full John Galt for a while. But now - wealth inequality is tearing the US apart, and will one day soon become (more) violent. You look at countries with the best outcomes - education, health, happiness - they're almost uniformly what Americans would call socialist. I'm just not arrogant enough to believe that the US can't learn from those, especially given it presumably wants to still be considered a world leading country. If you want to see how Ryan economics works, go check out Kansas. The GOP put in massive tax cuts there with big promises, and now kids can't even go to school 5 days a week because they can't afford teachers.
