Really would have to depend on so many factors it's silly to even guestimate - but I'll try anyway.
If your home is in good repair and you're not eating off wire spools or plastic milk cartons, and your car is worth 1/2 of what your home's realestate value is worth, who cares.
However, if you're living in a total shithole and you've spent more money on your vehicle you use to drive to the welfare office or the unemployment line then you're fucking retarded.
I simplified my life a few years back. I had been living the life in corporate America - built my house from the foundation up (22ft vaulted ceilings, etc), had me a tricked out 4WD F-150, all the amenities in my house you could imagine. All that came crashing down in the course of a 15minute "meeting". I learned a life lesson right then - it don't matter what you have from a tangible sense, the only thing that matters is what you have in your life as people.
Sure I intend to be a millionaire or larger fiscally, but I'm not going to let all that money ever affect me again. I won't be pimping photos of my "mansion" or Ferrari on the boards bragging about how sexy and cool and successful I am. All that bullshit is just icing on the cake. I'd rather have an abundance of people around me that I love and love me than to have all the riches in the world. And that's the fact, Jack.
