"Heartless," "cruel," and "appalling" were just some of the adjectives progressive critics and analysts used late Thursday to describe the Senate GOP's newly unveiled trillion-dollar economic stimulus package which—by design—would completely deny direct cash payments to the poorest Americans while cutting taxes for corporations, dishing out tens of billions in bailout funds to major industries, and restricting paid leave benefits that were just signed into law this week.

"The Senate GOP package is an utter disgrace," tweeted Richard Trumka, president of the AFL-CIO. "It gives free money to corporations, ignores the health crisis, and does nothing to keep people working or help the unemployed. The labor movement will oppose this Main St. bailout of Wall St. with everything we have."

"I don't know how else to describe this but wantonly wicked. The poorest get zero; low-income households get half of what middle-income households get; and a kid counts for 40% of an adult."

The Republican plan, released as the economic fallout from the coronavirus outbreak continues to worsen, would provide means-tested cash payments of up to $1,200 per adult and $500 per child, with the precise amount dependent upon 2018 tax filings.

"Taxpayers with little or no income tax liability, but at least $2,500 of qualifying income, would be eligible for a minimum rebate check of $600 ($1,200 married)," the Republican proposal states. "Qualifying income includes earned income, as well as Social Security retirement benefits and certain compensation and pension benefits paid to veterans."

Observers were quick to point out a gaping hole in the Republican plan: Adults with no qualifying income would get nothing.

"I don't know how else to describe this but wantonly wicked," said Daniel Hemel, a tax expert at the University of Chicago Law School. "The poorest get zero; low-income households get half of what middle-income households get; and a kid counts for 40% of an adult."

Kyle Pomerleau, an economist and resident fellow at the conservative American Enterprise Institute, estimated that "roughly 64 million filers earning less than $50k would not receive the full rebate amount of $1,200/$2,400" under the GOP proposal.

"For a single filer, income must be at least about $23k to get the full $1,200," Pomerleau noted. "For married couple filing jointly, [adjusted gross income] must be about $47k to get the full $2,400."

Phase-in is bad, bad, bad (and so cruel.) Giving less to people who have less at a time of desperation is completely unacceptable. Really, is now the time to say people who are struggling deserve less? https://t.co/Eyy5lfk6OR — Charlie Anderson (@EconCharlie) March 19, 2020

Senate Majority Leader Mitch McConnell (R-Ky.) pitched the GOP proposal as a starting point for stimulus negotiations with the Democratic Party, but Democratic leaders quickly dismissed the plan as a non-starter.

"We are beginning to review Senator McConnell's proposal, and on first reading, it is not at all pro-worker and instead puts corporations way ahead of workers," House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer (D-N.Y.) said in a joint statement Thursday night.

Even two Republican lawmakers—Sens. Mitt Romney (R-Utah.) and Josh Hawley (R-Mo.)—dismissed the plan as regressive.

Relief to families in this emergency shouldn’t be regressive. Lower-income families shouldn’t be penalized — Josh Hawley (@HawleyMO) March 19, 2020

While skimping on aid low-income Americans, the Republican proposal—formally known as the Coronavirus Aid, Relief, and Economic Security (CARES) Act—contains generous gifts for big corporations and billions in relief for industries hit hard by the coronavirus crisis, including $50 billion for airlines.

The 247-page Republican legislation, according to the New York Times, "includes a raft of temporary changes to the tax code that would reduce the tax liability of large corporations, many of them overriding provisions in the 2017 tax overhaul that were meant to raise revenue to offset corporate rate cuts."

The bill would also "place new limits on a paid-leave program that Congress passed and Mr. Trump signed into law this week," the Times reported, "shielding small business owners from any costs of paid leave for workers affected by the virus—and limiting how much pay those workers could receive if they are forced to stay home."

"Senate Republicans are using the COVID-19 pandemic to cut corporate taxes again and stop you from getting paid sick leave," tweeted advocacy group Swing Left. "They called it the CARES Act because Mitch CARES about big businesses, not you."
