Costs of racing, and how some teams have more money than others or how some teams spend their money, has been a continual complaint for as long as I've been around racing (since the 1960s). And it's at all levels - not just NASCAR. Recently I was looking at some of my old Stock Car Racing magazines from the mid-1970s and found essentially the same complaints and problems people have today - only the names have changed (mostly). Some people were sure that NASCAR was headed to ruin due to disgruntled older fans, a faltering economy, a few big budget teams squashing the competition, involvement (pro and con) of auto manufacturers, and declining car counts. Thing is, although the issues and complaining haven't gone away NASCAR racing has soldiered on...
Fact: money can buy speed and money can trump effort and experience and sometimes even the rules. It is frustrating but it's not going away. Try to "save teams money" with rule changes and the teams just redirect their money into defeating those rules. If they divert money from TV deals to racers (for example), the racers will just add that money to what they're already spending. They will use it to increase their costs - they won't save it or use it to pay down their current debts. And while they spend their windfalls they will still cry about their costs.
It is possible for a relatively low-budget team to beat high-budget teams. Not easy, and it may also require some luck, but it does happen. But that's the way it is at the top ranks of any endeavor. Shouldn't bite off more than you can chew and then complain that you couldn't handle it. Put your head down and work even harder, or go find someplace else to play.
Yeah, there is some merit to the argument that because the racers are taking the biggest risks they should also reap most of the rewards. Problem is, racers often only focus upon their own situations and don't pay much attention to or don't understand the risks and efforts by the supporting efforts (sanctioning body, tracks, promotion, etc.). At the same time it is well known how much money some of the complainers already have, making it hard for the average Joe to feel much sympathy for them.
Go ahead and try to tweak the old business model into a "new" business model... although old models usually can be improved there is good reason why they have worked for so long. But don't try to buffalo me into believing that redistributing more money to racers is going to reduce their costs and bring more new teams to the sport - that redistributed money will just add to the money they're already spending, and create an even higher entry point for newcomers.
