This week, House Democrats released their proposed tax increases to fund Joe Biden's $3.5tn social policy plan. The biggest surprise: they didn't go after the huge accumulations of wealth at the top representing the largest share of the economy in more than a century. You might have thought Democrats would be eager to tax America's 660 billionaires whose fortunes have increased by $1.8tn since the start of the pandemic, an amount that could fund half of Biden's plan and still leave the billionaires as rich as they were before the pandemic began. Elon Musk's $138bn in pandemic gains, for example, could cover the cost of tuition for 5.5 million community college students and feed 29 million low-income public-school kids, while still leaving Musk $4bn richer than he was before Covid. But senior House Democrats decided to raise revenue the traditional way, taxing annual income rather than giant wealth. They aim to raise the highest income tax rate and apply a 3% surtax to incomes over $5m. The dirty little secret is the ultra-rich don't live off their paychecks. You might also have assumed Democrats would target America's biggest corporations, awash in cash but paying a pittance in taxes. Thirty-nine of the S&P 500 or Fortune 500 paid no federal income tax at all from 2018 to 2020 while reporting a combined $122bn in profits to their shareholders. But remarkably, House Democrats have decided to set corporate tax rates below the level they were at when Barack Obama was in the White House.
