I think the title of this (open access) paper tells its story pretty good. I hope you’ll find time to squeeze it in  😉
A large literature examines the addictive properties of such behaviors as smoking, drinking alcohol and eating. Daniel Hamermesh and Joel Slemrod argue that for some people addictive behavior may apply to a much more central aspect of economic life: working. Workaholism is subject to the same concerns about the individual as other addictions, is more likely to be a problem of higher-income individuals, and can, under conditions of jointness in the workplace or the household, generate negative spillovers onto individuals around the workaholic. Using the Retirement History Survey and the Panel Study of Income Dynamics, the authors find evidence that is consistent with the idea that high-income, highly educated people suffer from workaholism with regard to retiring, in that they are more likely to postpone earlier plans for retirement.
The evidence and theory suggest that the negative effects of workaholism can be addressed with a more progressive income tax system than would be appropriate in the absence of this behavior.
