Personally, I think that most jobs are meaningless. Most jobs are simply a means of continuing the economic process. An activity that provides money so that money can be spent. A continuous cycle of meaninglessness. Most jobs do not work to solve real world problems like equitable resource distribution, endless consumption, climate change, pollution...etc. Most jobs are nothing more than a means of getting money.
In term of meaning, your job, like my job, like most jobs, serves about as much purpose as any other - (none). So you may as well continue to do it.
Keep the ball in the air. Keep the merry-go-round spinning. Keep this pointless cycle going.
