Yep, that's the danger of Googling something without a proper background. There is a season pass that the general public can buy, but it is quite different from the Cast Member version. https://forums.wdwmagic.com/threads/cm-silver-pass-question.906317/ versus https://disneyworld.disney.go.com/passholder-program/benefits-of-becoming-a-passholder/
No I don't think their perk is $1400. If it is a Cast Member Silver Pass, they can get three people plus themselves in to any park every day of the year for free. If you have family come over it's more than $100 per person per day. These tickets always include a Park Hopper option, adding another $40-50 in cost. If you use this perk 20 times per year for 3+1 people (which is definitely within reason), that would be more than $8000 and up to $12000 if you include the Park Hopper option. Maybe you could get that cheaper with season passes, but those are tied to an individual. $1400 is way, way off .
