You should probably be asking Biden then,

(Sep 10, 2020) Joe Biden pledges to roll back Trump's corporate tax cuts on 'day one,'

Democratic presidential candidate Joe Biden pledged in a CNN interview (transcript) on Thursday to undo President Donald Trump's corporate tax cuts on "day one" of his presidency. But it may be difficult for Biden to stick to that ambitious timeline since overhauling the tax code requires Congress to act.

(March 22, 2021) Why Biden won’t be able to totally undo Trump’s tax cuts

President Joe Biden got almost everything he wanted with his $1.9 trillion economic rescue plan. Biden campaigned on hiking the corporate rate from 21% to 28%. Prominent business groups are warning against the effort to roll back the 2017 Trump tax cuts, which lowered the corporate rate from 35%. Wall Street, however, is hardly freaking out about the potential of unwinding the Trump tax cuts. “Equities appear to be pricing optimism around infrastructure spending but little concern about tax hikes,” Goldman Sachs strategists wrote. Rick Rieder, BlackRock’s chief investment officer, "the US economy can “definitely” withstand higher corporate taxes. I think 21% is too low,” Goldman Sachs expects Biden’s next fiscal plan will include at least $2 trillion in infrastructure spending and could reach $4 trillion if it also funds healthcare, education and other initiatives.

(September 13, 2021) Democrats Hope To Undo Many Trump Tax Cuts To Fund Biden's $3.5 Trillion Budget Plan

Democrats hope to unwind many of the tax cuts Republicans enacted under former President Donald Trump as a way to pay for the majority of the $3.5 trillion spending bill. House Ways and Means Committee Chairman Richard Neal, D-Mass., released details Monday of a plan that includes increasing the top corporate tax rate to 26.5%, up from the current rate of 21%. Leaders such as House Speaker Nancy Pelosi, D-Calif., call the bill an effort at transformational change. At an event last week in Connecticut, Pelosi said the legislation working through Congress now "is about a vision for our country that is transformative, that frees people to reach their aspirations without concern that their children or their parents or their disabled relative are not cared for."

(Aug 11, 2022) Democrats ran on undoing Trump's tax cuts for the rich. But they're here to stay.

The 2017 Republican tax cuts survived a Democratic-controlled House, Senate, and White House largely intact — and they're likely here to stay. Top Democrats conceded they fell short of their original ambitions, citing the need to muster unanimity in a caucus that spanned the ideological spectrum from progressives to fiscal moderates. "In these kinds of debates, you always kind of set out where you want to go," Sen. Ron Wyden, chair of the Finance Committee, told Insider. "When you're looking for 50 votes, you don't get everything you want."

(June 18, 2024) Biden ramps up push to end Trump's tax cuts for the wealthy, highlighting the choice in the 2024 election

“If Trump gets elected, he’ll cut taxes for him and his rich friends at the expense of working families. We can’t let that happen,” Biden said last week on social media. Biden’s recent budget and a memo Thursday by top Biden economic adviser Lael Brainard laid out the White House’s vision for bringing in new revenue: raise the corporate tax from 21% to 28%.

Sen. Elizabeth Warren, D-Mass., said in a speech Monday: “The 2025 tax fight will create a huge opportunity to break with decades of tax-cutting political orthodoxy and reshape the tax code to reflect our nation’s values by raising taxes on the wealthy. That’s what Americans across the country are demanding, that’s what Joe Biden is running on, and that’s a big reason why Joe Biden will win in November. Next year, we must raise taxes on giant corporations and billionaires.”

tl;dr

• Corporate tax dropped from 35% to 21% by Trump in 2017 (TCJA)
• Biden campaigns "Day 1!" corporate tax 21% to 28% (2020 election)
• 2021, eh maybe we'll do 26.5%
• 2022, Shit! Sorry guys, we aren't a cohesive bunch (but student loans are next, we promise)
• 2024, Elect Biden! We will raise taxes to 28%! (not the original 35%)

I read the comments above, I saw @ModestMeme@lemm.ee with 18 upvotes and 1 downvote. I was confused and decided to look up an article so I'm not just blindly tucking something false into the back of my head (conservative relatives and area, I have to have my shit together when I'm talking in public around here).

I just spent the last 2 hours, for you beautiful fuckers, going down all these rabbit holes and reading article after article and constructing this timeline instead of making fried rice. Please don't be like ModestMeme and at least put one singular link up if you're trying to declare something as factual. You might find in your search that you were misinformed and let everyone know for the love of god. We need to keep our facts and shit together so we can all push forward together without misconstruing how we got here in the first place.

Didn't Democrats hold the house and senate for 2 years?

Gestures wildly at the Trump administration
