I can assure you ticket prices have risen far more than the cost of staging a parade.
Put another way. They can more than afford it.
Actually I doubt it.... 10 years ago the 1 day MK ticket was $71 today it is $101 and increase of 42%.... minimum wage 10 years ago was $5.85 vs today's $8.10 an increase of 38% though that leaves out the other increases in costs associate with labor, the affordable care act pushed costs significantly higher for the employer paid insurance.... So honestly I can see how the price increase for the tickets has pretty much been on pace with a lot of the costs involved in putting the parades on.
