Of course he isn't, all this bullshit lately has been for the express purpose of avoiding having to change the way he lives.
What's truly going to fuck him in the end isn't his spoiled income, though. It's his entitlement to
spending a shit ton of money as if it will always be there. The relevance of Phil's perpetually cushy life cannot be overstated. It may suck in a lot of ways, but not financially. He has never known such a hardship as not having money, and it fucking shows more than anything else about him does. Phil managed to go bankrupt after making six figures for years without investing in an actual business that went belly-up in spectacular fashion, or buying a bunch of property that proved to be too costly to maintain after some unlikely and unforeseeable disasters struck. He did it by being stupidly wasteful. He did it by having the "Oh well" attitude that
@Salubrious referenced above.
That doesn't happen in a vacuum. It comes about after many years of being a spoiled shit when it comes to availability of money. As much as he is sweating lately, it's not over sheer survival, it's over the continuation of the undeserved gravy train. He is not worried about simply making it, he wouldn't know a damn thing about that worry.
One day, I hope he does, then maybe he'll finally fucking learn. Doubtful, but if anything will do it, it's the day he has no money coming.
