A few notes on wage increases attributed to the tax cut. First, unemployment is back below pre-crisis levels, but wage growth still low -- economists have been wondering when wages would start to rise 1/ 
So wage-hike announcements are what we would expect to see regardless of tax cut -- indeed, Walmart has been raising wages for several years. But there's an obvious incentive for corporations to give tax cut credit for wage hikes they would have done anyway 2/
Furthermore, the theory behind the tax cut, such as it is, says that wage increases should take time. It's lower taxes -> more investment -> larger capital stock -> higher demand for labor. Not supposed to translate into wage hikes in year one 3/
So this is all about currying favor with Trump by saying nice things while doing what you would have done anyway. And Walmart's big quiet layoffs just add to the story. Funny how it doesn't blame the tax cut for its decision to close Sam's Clubs across the country 4
