A lot of honest answers here. To address one aspect of what the OP may have been thinking, no one on earth buys a $10,000+ bass because they need it. They buy it because they can, and because they want it.
That's okay; no harm in that, and it supports some makers creating things with really great craftsmanship. Fodera, Alembic, Wal, the craftsmanship is just marvelous to look at. The only downside, to me, is what seems like a widening gap in average affordability. You have to spend around $1300 new to get even a mass-produced U.S.-made bass. Add in a few more advanced features, a bit more handmade stuff, and you're suddenly in $3,000-plus land. Sometimes it feels like the middle class is dying in the guitar world, just as they say it is in the real world.
That's one reason my comfort zone is well-engineered but reasonable options. My Subaru Forester and my EBMM Sterling are much better values, to me, than their much-higher-cost counterparts. My '80 Yamaha BB800 is more of a cool vintage piece to me than the comparable Fender that costs 4 times as much, and my '75 Fender P is cooler to me than one made a few years earlier that costs twice as much. Those kinds of choices suit me. There's a little thrill in being able to buy something, but I honestly don't think I'd be any happier with a $10K bass than I am now. It reminds me of that recent study that found that happiness peaks at making around $70K per year. Even I had trouble believing that when I read it, but it makes sense. So much of our societal system grills into us the notion that unlimited more is better, but it isn't so.
So you guys with the highest-dollar high-end basses, I am happy for you. Those basses are awesome. I envy that level of freedom of choice. But I expect we're equally happy with our basses. I once owned an Alembic, briefly, and while it was marvelous, it never made me 1/10 as happy as I was when I first pulled my '80 Yamaha BB800 out of the gig bag it was shipped in. It's one of the least expensive basses I own, and it was love at first sight - priceless.
