Maybe. I'm not sure the math maths. What do you suppose one's net worth has to be to get to the point that income does not matter? And how many households have that net worth?
For example:
My employer's endowment spend policy is: 4.5% of the average balance over the past 28 quarters. Given the ordinary rate of return in the market, that's pretty close to (and a little less than) the "4% rule". So, for assets to replace an income stream of $X in a way that tracks inflation, you need assets of ~25 times $X.
In other words, if you want to generate $100,000/year---and that's pretty solidly middle class, not wealthy---you need an asset base of $2.5M.
That puts you in the upper less-than-10%, and I suspect Disney's addressible market is larger than 10% of the US.
Where I believe the "asset class"
does show up is in some of the upper-tier offerings: Club 33, the various park tours, hotel suites, etc.
