Mark Zandi also voiced skepticism that the wealth tax provision in Warren's plan - a key funding mechanism - will produce predicted levels of revenue because those targeted by the tax will seek to dodge it
Zandi believes Warren may still be able to make up the difference through other taxes in her plan
A key part of Warren's revenue calculations to pay for her healthcare overhaul comes from a new tax on the wealthiest 1 % of U.S. individuals, or a " wealth tax "
Warren initially proposed a tax that would impose a 2 % federal tax on every dollar of a person's net worth over $ 50 million and an additional 1 % tax on every dollar in net worth
Zandi, and the other economists who signed the letter, estimated the tax would generate an extra $ 3 trillion in revenue between 2020 and 2029, part of $ 20.5 trillion they say can be generated overall through additional taxes, but without raising middle-class taxes
