On the campaign trail in 2015, Donald Trump said it was “disgusting” that a big corporation could escape taxation by using bookkeeping tricks to shift profits out of the United States.

Now the Trump administration is thinking about making it easier to play those tricks. Bloomberg reported this week that the Treasury Department, in a development sure to gladden the hearts of the corporate class, was considering a rollback of rules written by the Obama administration to prevent the very kinds of shenanigans Mr. Trump once condemned.

While Congress focuses on the question of whether to impeach Mr. Trump, the potential change in tax policy is a reminder that the wheels of the government grind on — and that Mr. Trump’s administration continues to make decisions that are bad for most Americans.

In recent months, the Agriculture Department has decided to reduce inspections at the slaughterhouses that process the nation’s pork; the Environmental Protection Agency has decided to let farmers and factories dump toxic chemicals into thousands of acres of previously protected wetlands; and the Labor Department has ruled that states can perform drug tests on applicants for unemployment benefits, allowing Texas, Mississippi and Wisconsin to begin efforts to curtail aid for people who need help.
