My dad for example would be classified as a "middle class" millionaire. Nowhere near as much wealth as what we saw in this video, but still enough (his liquid net worth's around $4M right now) to buy "middle class" luxury cars (BMW/Merc/Lexus/Audi) outright for my younger brother and myself.
Most people might call me spoiled but I don't think that term really applies. It has an unwarranted negative connotation attached to it. "Spoiled" is when you are pampered but don't really appreciate it. I can assure you I appreciate every bit of financial support (more like excess) I've received over the years.
If I had $1B or $100M, I'd have no problem buying my 24 or 25 year old son a Lamborghini or something. Life's too short.
