Mostly because when you’re writing a fictional story, you need to remove everything that isn’t necessary for the plot. Is your story about racism? Then your ghost being racist makes sense. Otherwise unless it’s a gag it slows down the plot.
If we wanna get REALLY picky though…
Most ghosts probably aren’t speaking modern English either. A LOT changes in 200 years, how much slang rose and fell in that time? How much did accents change?
The concept of time was massively different too. Keep in mind before trains visiting a state could be weeks not hours. Could explain why ghosts are so patient though.
There’s also just vast differences in priorities, imagine a life where water is a constant mental calculation like your battery life on a phone. If they’re old enough that was the norm.
The sad thing is there’s not a lot of good advice right now.
The world is VASTLY different than 50 years ago. No you can’t just talk to the boss of the building and ask for a job.
The insane numbers game that job applications have become is so opaque that any advice in it is about as useful as sacrificing a goat.
Every company wants to remove as many humans as possible from its payroll. Covid and AI have proven this beyond a shadow of a doubt, loyalty means absolutely nothing now.
Just surviving in this current environment is a brand new challenge and field.
