I'm not fully sure of your argument here mate. Are you saying Moores and Parry are responsible for the massive demand for Liverpool season tickets that has spanned the last 2 decades? It doesn't surprise me Everton are able to give customers more freedom in the season ticket allocation and availability. They do not have a fan base (or historical success attracting fans) that compares.
No, im not saying Moores & Parry are responsible for the massive demand. I'm saying that when Ferguson, Edwards and the clan at United were investing in their club, the structure, the commercial side, the stadium, the facilities etc., Moores was delegating everything to Parry who, ultimately, failed to commercialize the club properly, failed to wrap transfer targets up quickly enough, failed to sell the club to decent custodians without seemingly any due diligence whatsoever, and - worst of all - failed to expand/build a stadium, which is why we are talking about this ST shambles.
