  • Entrepreneur Andrew Yang, whose profile in the primary race has risen in recent months, told CNBC's John Harwood that a wealth tax could be a "disaster in practice."

  • Progressive candidates in the top tier of the primary have called to raise taxes on the wealthiest Americans to pay for a bevy of social programs, such as "Medicare for All" and tuition-free college.

Some of the top contenders in the Democratic presidential primary have called for a wealth tax on America's biggest earners. But entrepreneur Andrew Yang, whose profile in the primary race has risen in recent months, told CNBC's John Harwood that the policy could be a "disaster in practice."
