The White House on Friday unveiled plans for a new effort to ramp up testing for Covid-19, which experts say is an essential part of limiting the spread of the virus. This chart from Vox gives a sense of just how far the U.S. has to go to catch up to other countries that are dealing with the pandemic, including South Korea, the leading virus screener with 3,692 tests per million people. The U.S., by comparison, has done about 23 tests per million people as of March 12.

The Air Force has scrapped a planned upgrade of its B-2 stealth bomber fleet — even after spending $2 billion on the effort — because defense contractor Northrup Grumman didn’t have the necessary software expertise to complete the project on time and on budget, Bloomberg’s Anthony Capaccio reports, citing the Pentagon’s chief weapons buyer.

Ellen Lord, the undersecretary of defense for acquisition and sustainment, told reporters that the nearly $2 billion that had already been spent on the program wasn’t wasted because “we are still going to get upgraded electronic displays.”

Bernie Sanders wants to eliminate $1.6 trillion in student debt, to be paid for by a tax on financial transactions, but doing so won’t be easy, says Josh Mitchell of The Wall Street Journal.  

The main problem for Sanders is that most Americans don’t support the plan, with 57% of respondents in a poll last fall saying they oppose the idea of canceling all student debt. And the politics are particularly thorny for Sanders as he prepares for a likely general election run, Mitchell says: “Among the strongest opponents are groups Democrats hope to peel away from President Trump: Rust Belt voters, independents, whites, men and voters in rural areas.”

That’s how much Michael Bloomberg is spending per day in his pursuit of the Democratic presidential nomination, according to new monthly filings with the Federal Election Commission. “In January alone, Bloomberg dropped more than $220 million on his free-spending presidential campaign,” The Hill says. “That breaks down to about $7.1 million a day, $300,000 an hour or $5,000 per minute.”

The leading candidates for the Democratic presidential nomination have all proposed increasing taxes on corporations, including raising income tax rates to levels ranging from 25% to 35%, up from the current 21% imposed by the Republican tax cuts in 2017. With Bernie Sanders leading the way at $3.9 trillion, here’s how much revenue the higher proposed corporate taxes, along with additional proposed surtaxes and reduced tax breaks, would generate over a decade, according to calculations by the right-leaning Tax Foundation, highlighted Wednesday by Bloomberg News.

The federal government’s total non-defense discretionary spending – which covers everything from education and national parks to veterans’ medical care and low-income housing assistance – equals 3.2% of GDP in 2020, near historic lows going back to 1962, according to an analysis this week from the Center on Budget and Policy Priorities.

The Committee for a Responsible Federal Budget estimated this week that President Trump has now signed legislation that will add a total of $4.7 trillion to the national debt between 2017 and 2029. Tax cuts and spending increases account for similar portions of the projected increase, though if the individual tax cuts in the 2017 Republican overhaul are extended beyond their current expiration date at the end of 2025, they would add another $1 trillion in debt through 2029.

Are interest rates destined to move higher, increasing the cost of private and public debt? While many experts believe that higher rates are all but inevitable, historian Paul Schmelzing argues that today’s low-interest environment is consistent with a long-term trend stretching back 600 years.

The chart “shows a clear historical downtrend, with rates falling about 1% every 60 years to near zero today,” says Bloomberg’s Aaron Brown. “Rates do tend to revert to a mean, but that mean seems to be declining.”

Lawmakers are considering three separate bills that are intended to reduce the cost of prescription drugs. Here’s an overview of the proposals, from a series of charts produced by the Kaiser Family Foundation this week. An interesting detail highlighted in another chart: 88% of voters – including 92% of Democrats and 85% of Republicans – want to give the government the power to negotiate prices with drug companies.

From Gallup: “A record 25% of Americans say they or a family member put off treatment for a serious medical condition in the past year because of the cost, up from 19% a year ago and the highest in Gallup's trend. Another 8% said they or a family member put off treatment for a less serious condition, bringing the total percentage of households delaying care due to costs to 33%, tying the high from 2014.”
