Trump's answer to pretty much any question is either more oil drilling or tariffs. Few think it will work.

A series of appearances in recent weeks have solidified a truism about former President Donald Trump: Nearly every economic challenge, from deficits to the fraying social safety net, can seemingly be solved with more oil drilling or new tariffs.

It will be "so easy," he is fond of saying — and will also bring in waves of money.

But economists and other experts are skeptical on multiple fronts: Would it really be that easy? Would it bring in anywhere close to as much money as the former president thinks?

Not to mention whether such policies might cause more problems than they solve.

Yet it hasn't slowed Trump, who at a series of events in recent weeks — from the recent debate to an economic speech to multiple rallies and press appearances — has promised that America's coffers will be overflowing if he wins in November because of these twin policies.

"We're gonna have so much money coming in," he said at a speech last week in New York on the topic of tariffs. Oil is additional "liquid gold," he added Thursday during a stop in Arizona.

Trump has in turn promised that these funds will pay for nearly all of his other ideas. Everything from lowering deficits to defeating inflation to lowering taxes to cutting prices in half, he says, will be possible, with enough left over to create a new national sovereign wealth fund.

In one widely noted exchange at the Economic Club of New York, Trump fielded a question on what childcare policies he'd champion but answered even that by returning again to tariff revenue.

"Those numbers are so much bigger than any numbers we are talking about, including child care," Trump said in a meandering and widely criticized answer.

The rhetorical tack from Trump is also a way to try and wave away questions about the costs of his other ideas, from extending his 2017 tax cuts to a call for free IVF coverage to a new policy announced this week to end taxes on overtime.

Trump also recently endorsed a government efficiency commission, to be headed by Tesla CEO Elon Musk, that he says will generate trillions more.

'Liquid gold'

Oil drilling is the area where the GOP nominee returns perhaps the most often, promising to unleash the sector at nearly every campaign stop.

What he often overlooks is that the US, under the Biden/Harris administration, is currently drilling more oil than during Trump's term. In fact, the US is currently producing more than any country in history.

But Trump nonetheless promises that his plan for the sector will not only bring in additional billions, it will also cut energy prices in half.
