Don’t forget: Trump is the choice of the working stiff, the coal miners and Walmart clerks, the single mothers and displaced factory workers.

Suuure he is.

In the final months of the Obama administration, Walmart was under pressure from federal officials to pay nearly $1 billion and accept a guilty plea to resolve a foreign bribery investigation.

Barclays faced demands that it pay nearly $7 billion to settle civil claims that it had sold toxic mortgage investments that helped fuel the 2008 financial crisis, and the Royal Bank of Scotland was ensnared in a criminal investigation over its role in the crisis.

They were saying no, we won’t – and along came Trump to say there there, you don’t have to.

Federal prosecutors and the Securities and Exchange Commission have yet to charge Walmart, and the Justice Department reached a much lower settlement agreement with Barclays in March, for $2 billion. R.B.S. paid a civil penalty, but escaped criminal charges altogether.

Across the corporate landscape, the Trump administration has presided over a sharp decline in financial penalties against banks and big companies accused of malfeasance, according to analyses of government data and interviews with more than 60 former and current federal officials. The approach mirrors the administration’s aggressive deregulatory agenda throughout the federal government.

The New York Times and outside experts tallied enforcement activity at the S.E.C. and the Justice Department, the two most powerful agencies policing the corporate and financial sectors. Comparing cases filed during the first 20 months of the Trump presidency with the final 20 months of the Obama administration, the review found:

• A 62 percent drop in penalties imposed and illicit profits ordered returned by the S.E.C., to $1.9 billion under the Trump administration from $5 billion under the Obama administration;

• A 72 percent decline in corporate penalties from the Justice Department’s criminal prosecutions, to $3.93 billion from $14.15 billion, and a similar percent drop in civil penalties against financial institutions, to $7.4 billion;

• A lighter touch toward the banking industry, with the S.E.C. ordering banks to pay $1.7 billion during the Obama period, nearly four times as much as in the Trump era, and Mr. Trump’s Justice Department bringing 17 such cases, compared with 71.

Not just letting them get away with bad practice, but also throwing away all those billions.
