Ok, I will respectfully bite, and as I said in the other thread that comparing the skateboarding industry to any other does not properly compute.
Ok, so first off, I have not personally seen a TM or person in power ignore injury or handle it differently due to finances.
A few other things to consider. I believe James' house was in Alabama, and he skated for Fallen during its heyday, and I am sure had a few other good paying sponsors at the time. Although there was a worldwide recession, 2002-2012 was very very good for skaters that had all their bases covered. I.E. board, shoes, clothing sponsors. His time and choice of house are important ingredients to his situation, as every skaters situation is case by case.
Now skaters LOVE skating, right? If you do it, chances are it is your life. There aren't many "casual" skaters the same way your uncle might go see baseball games and buy memorabilia, yet doesnt regularly play baseball and maybe hasnt swung a bat in 3 decades. Why I am explaining this is because a disproportionate amount of skaters aim to achieve a sort of status, where as your uncle is not doing everything he can to join the team or see what he can get for free. This matters because this is how the market gets flooded.
"Oh they wont put me on so Ill start my own shit"
Now gatekeeping is a whole different conversation we will save for another time, but hopefully my point is clear. The percentage of skaters who would like to be sponsored or pro is much higher than the percentage of people who try to achieve status in other sport/artistic industries.
Now why does this matter? It dilutes the market.
Without revealing too much and being respectful, a very well known and appreciated skater told me they sell about 150 boards a month. Lets crunch some numbers. Ill use loose numbers for the sake of convo.
The shop buys them for about 45 dollars. And they cost 25 dollars to make. That leaves 3,000 for the company, yeah? Now the company has a building and employees and keeps the lights on, and pays for the graphic, about 200-500 dollars for freelance, or a salary artists wage. And it seems like the industry standard for companies with no minimums is 5 dollars a board. So thats 750 bucks. And its 1099. So this is before taxes. Now your suggestion of 35% of wages toward health or union leaves us at 487.50, not a liveable wage.
While it is a shame, the money just doesnt exist. The only way pros are taken care of is if we had much less people with names on their board. People forget while this is a physical activity and people confuse it with "sport", it is artistic in nature. People are creating footage and you either like it or dont. Buying a product with someone's name who you support goes a very long way. Because if I employ you, and pay 25 dollars an hour for 40 hours, I can quantify that. I owe you 1,000 dollars. But if you skate your ass off, kill it, and I give you 5 bucks a board, and we sell 100 boards, I can only justify giving you 500 dollars. I can't give you money that doesnt exist.
TLDR: If you like someones output and want to support, try your best to buy a product with their name on it.
Sorry for the rant, Im sure I have more points but you know, no need to make everyone read a novel. Its too nice outside for that
