I guess the way I look at is Ryan showed what his priorities are
Sort of. Lowering tax rates isn't exactly harmful to the economy, and it's something he
could get done.
However, he was working with a President who had run explicitly on
refusing to reform the entitlements. So, that was
not something he could get done.
When he ran as a VP candidate in 2012, part of that was getting Romney to commit to a platform of reforming the entitlements to make them sustainable.
Claiming that the first is somehow proof that the second or third didn't happen isn't a terribly convincing argument.
The GOP when he was in power cut taxes - that is what they DID. TCJA that you describe as a "slight decrease in nominal marginal rates" was obviously far more than that - it was a $1-2 Trillion tax cut, when the economy was in full employment, stock market healthy. So it increased deficits, rewarded the donor class, when no one can argue higher deficits were needed for the economy. It's no coincidence that it granted HUGE savings to...the donor class, with big reductions in corporate tax rates and the rate on pass-through income.
It's not much of a coincidence that the people who pay taxes will benefit when rates are cut, no. However, that Big Fancy Donor Class? It's mostly blue, nowadays - especially in the years under discussion, after Trump came on board.
The U.S. has the most progressive tax system in the OECD. Working backwards from that to try to claim that every tax cut's benefits go mostly to "the rich" is partisan jackassery trying to frame itself as math.
I'm interested and totally down for a good debate on the impacts of entitlement reform and tax reform, and the opportunities to combine the two. I'm not interested in spending a lot of time fielding what I consider to be bad-faith accusations that My Tribe Is For The People But The Other Tribe Is For The Bad Others. In this particular case, it's particularly poorly aimed because to the extent that the "Donor Class" had a lean post-2016, it wasn't towards Donald Trump's GOP, but towards the Democratic Party.
Furthermore, his "entitlement reform" plan (and it was a plan, not separate parts that we can ignore what we want) was also, you guessed it, a donor class dream come true. Cut rates, eliminated taxes on investment income, eliminated the estate tax, and then.....what do you know!.... imposed huge benefit cuts for seniors and the poor. It was a french kiss on the bare asses of donor class, and a big **** you to seniors and the poor who shouldered ALL the 'pain' of the 'reform.' It's just stupid policy, and it's no wonder it didn't pass. The donor class got their goodies, but why would anyone else support huge tax CUTS for the top 1/10th of 1% and massive pain for everyone else?
No, but opposition to it was only fueled by people who want communism and hate freedom and prosperity.
Last year, Rep. Paul Ryan (R., Wis.), Chairman of the House Budget Committee, unveiled the Path to Prosperity, an impressive fiscal plan that, for the first time in memory, put one chamber of Congress squarely on the record as favoring significant entitlement reform. Today, Ryan has put forth...

Paul Ryan's actual plan (rough outline) basically shifted current Medicare from a single-payer model to an Obamacare-like model, with a public option, a plan he built with Alice Rivlin, President Clinton’s former budget director.
Furthermore, the ACA DID cut Medicare spending. It wasn't a proposal, but actually passed, got into law. Do you give the Democrats credit for that accomplishment, that not one Republican supported?
No, for two reasons:
1. They didn't reduce Medicare spending to make the program more sustainable, but so as to shift those funds over to a brand new entitlement (Obamacare subsidies).
2. They didn't actually make the cuts. They immediately passed the "Doc Fix", rescinding the cuts, thereby proving correct the critics who said it was an accounting gimmick, and that, in fact, the program was funded by far more deficit spending than it had been sold with.
In fact the GOP ran on how bad it was for Medicare to cut benefits - bad Democrats!!
Simply deeply slashing medical provider reimbursements is, indeed, a very bad way to cut Medicare spending. That is what Democrats proposed to do, whereas Republicans did not.
