Yeah! A lot of this comes from a lack of agency in your daily life. You have to do all sorts of things just to stay afloat, leaving little to no time for yourself, so you take revenge at bedtime. The classic argument that salary and hours are no longer tied to productivity applies here; working less for more money reduces the need to spend your sleeping hours finding satisfaction.
I wouldn’t say this is a uniquely capitalistic problem, though. Capitalism is just a huge factor in the reduction of individual agency (unless you’re a capitalist and actually have agency) and it’s the most common setup we have currently. You could have the same lack of agency in another setup and see the same problem.
