Sox only have Devers and Casas (out) that can compete with the Yanks offensively. Houck and Crawford have pitched as well as the Yankees rotation, but everyone else has been less than.
Yankees have a higher payroll. Red Sox did a bad job developing players under Ben and DD. With Bloom, a lot of strides were made, but he drafted HS guys that took longer to develop so they just aren't ready yet. Also, there was no focus on pitching at all until Breslow. Sox are just hopelessly behind right now. It will take a few more years.
No reason to be permanently pissed about it since we can't fix the problem ourselves.
