No it's absolutely not. They run businesses, not charities. They are going to set their prices at the demand the market dictates, and people will pay that because that's how economics work.
This idea that billionaires should just lose money on ventures for the benefit of everyone else is silly, and is the complete opposite line of thinking that made them wealthy.
If you are priced out because of it, then that's that and it sucks. They don't owe you anything, and I guarantee this hand-me-down mentality you are pushing here stops immediately on the rungs of the ladder beneath you, which is likely 90% of the rest of the world.
First of all, you know next to nothing about me other than the fact that I'm an Islander fan, so while it might be easier for you to classify me based on your pre-conceived notions of people you've met in the past, fine, but the things you're spewing about who I am and my opinion on the 'hand-me-down mentality' couldn't be farther from the truth. I do my fair share when it comes to charity and I'll leave it at that.
People are going to go to the games no matter what the price is. It's not accessible to the vast majority of their fanbase and you're 100% right, too bad, so sad. And when it's not a pandemic, I'm with you (and that mantra) because that is how capitalism works; and there's nothing wrong with making money and there will always be haves/have nots. It comes across as tacky to gouge people at this time. You don't have to agree with me and I don't have to agree with you. You're certainly not going to change my mind on the matter either.
I don't know the full story behind the cost of operations behind the Nets and I'm not even going to pretend I do. I also don't know the exact price, but there's been rumors floating around that the number is high. In my eyes, and I'm sure I'm not alone in this regard, it looks tacky. They won't be the only team that does this though and at that point, I will also consider those teams/their owners tacky. I know my opinion means nothing and I know that this is the way that the market will be run. I'm also certain people will pay that price to attend. Doesn't mean I don't think it's wrong.
But by all means, protect the pockets of those billionaires today. Thankfully they have a bunch of people like yourself out there defending their actions.
