When loads of manufacturing jobs require a PhD.

I'm David Brancaccio, first to a spot where Kamala Harris and Donald Trump economic policies overlap.

Both candidates want to eliminate federal tax on

tips. Two and a half percent of the labor force earns money from tips. It's a

proposal that delights many and worries others. Here's marketplace's Stephanie Hughes.

More than a third of tip workers have incomes that are so low, they already don't pay any federal income taxes.

So if somebody's tax liabilities are zero and you want to reduce their tax liability,

you can't go any lower.

That's Indiana University Accounting Professor Bridget Stomberg.

She says there's concern that these tax policies would

treat workers with similar incomes differently. For example, you make $32,000 a

year as a cashier and I make $32,000 a year as a waitress and part of my income is tips and none of your

income is tips. All of a sudden I pay less tax than you do just by virtue of the fact that I'm a waitress and you're

a cashier.

And it could make more people want to trade in being a cashier for being a waitress.

Garrett Watson, to senior policy analyst at the Tax Foundation.

I would expect to see the restaurant industry industries that have tipping as a major

source of income to see more interests by workers if this were to become law.

The Tax Foundation estimates that eliminating income taxes on tips would cost at least

107 billion dollars in revenue over 10 years.

I'm Stephanie Hughes from Marketplace.

Consumers are expecting inflation to become less of a problem, but they're worried about paying what they owe now.
