Only if you actually think and say it does it become elitism, just owning pro equipment does not make you elitist.
Very true but owning high spec gear and then trying to illustrate it's purposes or why it's better/more capable/reliable etc is often mistaken for or can generate accusations of elitism. It's happened many times on TP and other forums.
I once won 8 pool games on the trot using a broom handle, this was down to my talent not the kit I was using, I got the job done; on the flipside if I had have had a pool cue I would have got the job done easier and would have been equipped for all eventualities.
same applies here IMO, I can get great shots with a kit lens, but give me the same lens 2.8 stylee and ill also get those shots plus have an easier time in low light. :shrug:
Whilst winning several games of pool with a broom stick is very impressive and also fun, (there's probably a very interesting DVD tutorial in there somewhere

) but the analogy doesn't quite cover the entire 'picture' in this instance.
A pool cue and a broom handle have too many things in common, they're long, thin and solid wood for starters.
If you were to directly compare the use of say a 400mm f/2.8 prime and then a 18-200mm F/5.6-6.3, that broom handle can become a rolling pin in most eventualities.
A kit lens offers a world of potential initially but most tend to move on and develop with different spec gear. Kit lenses are basic, entry level introductions largely constructed with cheaper materials and are often sold on to ease the funding on the next, more experienced, higher spec choice of purchase. The more pertinent issue is that anyone who cares deeply about their output, or about what they are selling to their customers, about how they earn their living etc, takes a certain level of consideration for the quality they are offering and as a result they look for the
tools that fit their requirements and deliver them.
This roughly explains why the search for reliable/quality tools is considerably important to those that use their tools to maintain feeding mouths, paying bills, sleeping soundly at night and also take a little pride in and enjoying their jobs.
There are also many circumstances however, that dictate which tools are required.
(Of course a higher level of skill has more potential than the standard of equipment, the two elements work in harmony, it's just that the skill element doesn't get confused or mistaken for elitism as often.)
The big 'but' is when were enter a more specific environment, let's again take sports for example:
Amongst the industry standard lenses used for major sports events, there will often be fast telephoto primes = very, very expensive pieces of glass to which there is
no substitute. Moving into closer proximity at major sporting events will result in ones arrest or at least ones abrupt ejection from the venue and the loss of ones job.
Pro Sports and Pro Wildlife photography are IMO, the most expensive base fields to equip oneself for.
No matter if you look at
second hand, older versions or MF alternatives, it's still a huge investment. You can buy a good car for the price of a good 400mm.
This acceptance and also attempting to inform some folk about it, is often considered or mistaken for elitism or snobbery.
These accusations, in my experience seem to stem from jealousy or a feeling of inadequacy when there really shouldn't be any of these feelings at all.
The am vs pro debate is a very good example of this, working photographers often perceived as disparaging, mean, ill tempered party poopers that are out to extinguish whoever fancies turning a hobby into a business with thier tales of massive expenditure, industry standards and the repercussions of making large mistakes in the initial infancy etc.
Or why was the 5.6 lens used inside a dark church during a paid wedding shoot when there was a 50mm 1.8 in your camera bag? etc...
Most of the time, there are circumstances that exists outside of our own, with totally different mechanics and methods of resolution. It's all about putting it all into context and considering them sensibly.
Convincing oneself that it's elitism or snobbery just seems to be wilful ignorance and it's not helping anyone.
