Boy, are they annoyed: Democrats are pooh-poohing the avalanche of announcements by major corporations that they’re giving their workers bonuses and raising wages after the passage of tax reform.

It’s classic left-wing disdain for anything big business does, even when it’s rewarding its workers — and even when those reaping the benefits include the Democratic cheerleading squad at MSNBC.

Following President Trump’s signing of the act, which lowers the corporate tax rate from 35 percent to 21 percent, leading companies began — in his words — “showering their workers with bonuses.”

AT&T announced $1,000 bonuses for its 200,00 workers. So did Sinclair, the nation’s largest TV broadcaster, for 9,000 employees, and Comcast, MSNBC’s parent company.

Wells Fargo and Fifth Third Bankcorp are boosting their minimum wage to $15 an hour — a major goal for Democrats these days — and many of the same companies also announced new business and philanthropic investments of up to $1 billion.

So what was the Democrats’ reaction when corporations began passing on their anticipated added profits to workers?

Democratic (and former Hillary Clinton) strategist Jesse Ferguson called it an attempt to “curry favor” by “playing to the ego of the president.”

House Minority Leader Nancy Pelosi claimed the AT&T bonus had already been negotiated as part of a new union contract and was an attempt to “pin a rose on this tax bill” — only to learn that it was an extra $1,000 bonus on top of the earlier one.

Many other Dems and their media supporters labeled it a p.r. stunt. MSNBC’s Joy Reid, who’ll soon pocket an extra $1,000, called it “corporate America trying to convince you that their naked greed is charity.”

It’s literally no-win with this crowd. As economist Steve Moore has rightly said: “Democrats are for jobs, but they’re against business.” That’s never been more obvious.
