I agree to a point, Pro....
but you have to admit, there was a lot more work involved in getting music back in the day.
You'd have to do your homework and subscribe to magazines to know what the hottest songs were...
you'd have to get in your car, and waste a little gas driving to the record store...
you'd have to find a way to store, organize and care for your lp's or 45's...
and if you were at a gig and didn't have a song, you could not download it instantly.
As for gear...owning the gear IS part of the qualifier.
In the past, the general public did not have (some of) the gear needed to do the job.
And they certainly did not own enough music to qualify.
These days, EVERYONE has a record collection on their phone.
Your point being what?
We also didn't have Mtv, American Idol, and a culture obsessed with reality level talent. I think your assessment of the music being "harder to get" back in the day is mistaken - It was easy but, no one was all that interested except a few odd ball DJ types.
What you have today is a society of "look at me" facebook types searching for a spotlight. Being the DJ is the fastest way to grab that spotlight - and everyone from Elvis impersonators to software geeks has grabbed for it.
The DJ community used to be a collection of electronic pseudo-musicians and dance music fanatics who were interested in how they could manipulate the tracks and move a crowd. Mobile DJs today tend to fall into two categories: the wannabe entertainers - from game show hosts and reality show rejects, etc. to computer geeks whose DJ skills are limited to the features of their favorite PC application. To think of DJing as an "industry" is like calling Facebook "corporate communication." DJing is now just part of today's electronic consumer culture.
If you listen to the self proclaimed DJ "industry" you will hear that they are not actually talking anything DJ related - they all about the "emcee" or "entertainment." Entertainment is something very different, even if it includes a DJ as part of the act. DJ skills are becoming obsolete as people replace them with software and editing tools. The value (price) of that service (is) will naturally decline. Those who aren't entertainers suddenly become photo-booth rental or up lighting vendors, etc. Find me a single "up-sell" that corresponds to a given DJ talent. There was a time when people paid more for better DJ skills, or specialized genres, etc. - now, there's an APP for that!
