"When government steps in arbitrarily with individual subsidies, favoring one business over others, it sets inconsistent, unfair, illogical precedent," she wrote
Friday in a "Young Conservatives" column. "Meanwhile, the invisible hand that best orchestrates a free people's free enterprise system gets amputated. Then, special interests creep in and manipulate markets."
"Republicans oppose this, remember? Instead, we support competition on a level playing field, remember? Because we know special interest crony capitalism is one big fail," Palin added.

But Palin said when the government chooses companies to favor, the American economy is "doomed."
"Politicians picking and choosing recipients of corporate welfare is railed against by fiscal conservatives, for it's a hallmark of corruption. And socialism," the former Republican vice presidential candidate said.

Palin -- who endorsed Trump early in the campaign -- is reportedly being considered to be Trump's secretary of veterans affairs or for interior secretary.
