Tiger, those other workers tend to be working for companies making a profit. I guess that's the difference right now. At least with the next few years, if these incoming teams work out, there'll be more money in the pot for all players. Mid-range players could start on an expansion team while fringe players get rotation spots.
I think the sport loses allot of fringe talent whom might develop later or come back from college at 24 and don't walk straight into a solid contract due to the poor salaries for Dev & 9/10 players.
I've heard the argument, and tend to agree, that 9-10 and down should realistically consider it a part-time gig. The drawcards are the top-end players and spending more on them would help in getting media attention and more fans. Further, you might have a 10th man on $40k and an 8th man in the rotation on $55-60k. Former might get 5 minutes across the entire season whereas #8 is playing 15 MPG.
9-10 could potentially be expected to make it to half the trainings and study or hold down a part-time job with the understanding of their coach and GM. Few years down the track and they might have the degree and an idea of whether they can make a career out of basketball rather than have stalled things. Ng and Tovey managed to do it though not everyone has the discipline or sway.
Not sure how the NBLPA would feel about reducing the minimum salary though.
