Mayor de Blasio just can’t quit attacking progress — no matter how lame his arguments get.

Consider his latest slams at Uber, the app-based car service that (finally) offers New Yorkers an alternative to yellow cabs.

Last week, de Blasio blasted the company for not charging the 50-cent MTA tax for cab rides — as if any business anywhere collects a tax it doesn’t have to.

Anyway, Uber noted it “generates far more​ tax revenue” than taxis — thanks to sales tax averaging about $2 a ride.

But the details don’t matter. The real point of de Blasio’s gripe was to renew his efforts to choke off competition to the yellow-cab industry — which, uh, gave $550,000 to his 2013 campaign.

Remember his plan to freeze the number of Uber cars? His excuse was as rich as the one from Gov. Chris Christie’s aides in Bridgegate: a “traffic study.” Public pressure forced the mayor to back off. Yet he was soon lashing out at Uber again.

Never mind that crushing Uber would mean less cash for hard-working, low-income drivers and fewer options for riders — the kind of things a progressive should oppose.

Fact is, Uber itself represents progress. Riders love getting car service at the tap of an app — and usually at reasonable prices.

And they easily see through de Blasio’s excuses: In this month’s Quinnipiac poll, 65 percent of New Yorkers said they believe officials like the mayor target Uber because they get mountains of cash from yellow-cab folks.

“‘Progress’ isn’t always progressive,” mayoral aide Karen Hinton tweeted in July, in defense of de Blasio’s Uber-bashing. No, for her boss, being progressive apparently means taking money from a special interest and then shielding it from competition — and to hell with regular New Yorkers.

If that’s true, who needs “progressives”?
