The prices just make me sad

Is it just me?? I look at the cost of park admission and it’s just depressing. My wife and I were looking at a chance to do a quick surprise trip with our kids (7 & 5). I found a good deal on flights and accommodations… all in we were looking at about $2500ish for flight, hotel, rental car, and parking (with credit card points covering the flights). And tickets to the parks for 5 days are coming in at nearly $2500 on their own and not even during a busy time! We had set a budget at $5k and we just can’t bring ourselves to drop this kind of crazy money… and it makes me really sad. I make a pretty decent living and I’d say we are upper-middle or middle-middle class (idk where that line falls) and WDW is almost out of reach. Even if we go dirt cheap at the parks, eat breakfast at the hotel and bring lunch, there’s still no way we’re doing it for less than $1k per park day. Who can afford that?!
I understand the supply and demand argument but that doesn’t make it suck any less.

Update: I didn’t expect this to get so many responses but thanks for the many great suggestions. A few details I had left out of my original lament that may help color in our decision-making: 1) the length of the trip was dictated more by the cheap flights than anything else. The prices changed drastically if the travel dates changed.
2) some family health challenges are a big part of our strong preference for a rental car; we’d love to skip that cost but would have to look closely at the transportation… the rental car and parking is not the biggest cost but it’s not trivial either. 3) we were having difficulty finding availability at Disney hotels so we’d turned to an on-property hotel that we’d liked before. We have now learned through a planner that there are rooms available with Disney so that may also affect the decision… it’s astonishing how difficult it can be to navigate Disney’s hotel options!
