An example using one of my other favorite things... CYCLING!
We have person A. He is a dentist who has picked up cycling as a weekend health and all around fun past time. 'A' has the money, being a dentist, to drop a cool $3000 on a nice carbon fiber road bike, with a snazzy spandex suit that he can pedal around with on the weekend.
We have person B. 'B' is a serious cyclist. 'B' competes in cat. 4 road races during the summer and has also taken up cyclocross in the winter. Now, to kill time and stay in shape, 'B' has also been compeeting in the local Velodrome as well as a tri-athalon or two per year. 'B' is so serious about this that he has spent about $5000 on each bike for each race, which has been custom made for his height and weight. Cycling for 'B' is a full time job and it is how he makes a living. 'B' is puuuuure pro.
We have person C. 'C' is a bike messenger on the mean streets of New York city. 'C' is on his bike for hours upon hours 5 or 6 days a week. Now, NY is a rough place, and 'C' doesn't need a fancy carbon bike. 'C' has dumpstered a frame and built it up himself, stripping off superfluous gears and/or braking systems. If that fails, 'C' has no problem rocking a WalMart bike that gets him from point a to point b. All in all though, 'C' doesn't spend more than $100 or so on any of his bikes.
Finally, we have person D. 'D' is a pure commuter. However, unlike 'C', 'D' has a nice spot to lock his bike up at work and can afford to spend $2000 on a comfortable bike. However, 'D' is aware that he lives in a city and theft happens, so 'D' also has a neat little hybrid bike that only set him back about $500. Recently, 'D' has been enjoying his hybrid even more than his nice commuter bike.
Now, the same story can be applied to almost ANY sort of wide-ranging hobby. In our bass world, 'A' would be the same affluent dentist that has a super nice Sadowsky and a nice micro combo that he mainly uses in his bedroom... but will play out on occation. 'B' would be the super pro with a bajillion different basses for each job. 'C' would be the less-affluent but still giging bassist that has no problem rocking an SX or Squier as long as it gets the job done. Finally, 'D' would be the guy that gigs some times and jams with his friend, he may have a nice MIA Fender... but he's also hip to the pure playability of his SX.
So the moral is... everyone is different. Everyone's reason and methodology for playing bass is different. Some guy loves his $4000 Ritter just as much as the guy that loves his SX. You can't put a price on passion and you can't make judgements on other people's said passion. No-one has the right to bash someone's $4000 high-end boutique bass just as no one has the right to bash the other guy's $80 SX.
TL;DR - Play your own bass to the best of your own ability and play it so that YOU are happy.... **** what anyone else thinks.
