What's wrong with SeaTac's $15 min wage in 1 photo — Local businesses are now adding 8.25% "living wage surcharge" pic.twitter.com/IMifQRIWhN

…basically, what happened there is that Seattle raised its minimum wage to $15/hour: and at least one business involved promptly passed along the costs to the consumer as a ‘living wage surcharge.’ Couple that with what appears to be a sales tax of 11% and suddenly a bill for $84 is well along its way for becoming one for $105. And here’s the important thing: there are people who will pay $84 for this particular service (ie, keeping their car at the airport for when they get back), but not $105. They’ll instead have somebody drop them off and pick them up, or find a cab service that won’t charge them $105 for two trips, or maybe even go to a different airport where things are cheaper. Put another way: less economic activity. Less money in circulation. Less people getting money for services.
Because that’s what happens when you tax things. You get less of whatever it is that you’re taxing. This is known.
PS: The people telling you different… well, I suppose some of them have worked at real jobs. …Some.
