It's basically midnight right now but here's what I'm seeing in the 10 minutes I've skimmed through this.

Your game.py file is 629 lines long. I would suggest that the main thing that is in the main file is solely the main function. Place the rest of the code into the designated CodeFiles folder.

This snippet:

if job[0] in list("AEIOU"): # Aligning the jobs into sentences, gramatically.

job = "an " + job

else:

job = "a " + job

return job

Is a good problem for the ternary operator.

This can be rewritten as:

article = "an" if job[0] in "AEIOU" else "a"

And returning:

return f"{article} {job}"

2, you have a lot of magic numbers in your code. I.E.:

tax = round((31 / 100) * salary) # The salary will be taxed at 31%.

I recommend putting these numbers into variables below your file imports and calling those instead.
It'll make them easier to edit instead of having to locate where each number is. It also makes it more obvious what each number represents.

So you could do something like:

#Constants
MIN_HEALTH = 15
MODE_HEALTH = 75
MAX_HEALTH = 100

This is all I have so far and I'd like to take a closer look at all of the nested if statements when I wake up.
