Using your data and this site's, it seems like the increase has actually been dropping over the past 30+ years; the price at Aspen increased by 2.3 in the decade between 1975 and 1985, then 1.7 between 1985 and 1995, and 2.1 between 1995 and today, which is 18 years, so if you correct for that, about 1.2 for any decade since 1995. So while the absolute price increases ran well ahead of inflation, the rates of those increases have been running counter to inflation. Eg, we're getting robbed, but now only out of one pocket instead of two.
You are using real dollars instead of inflation adjusted. To draw meaningful conclusions with comparing prices across decades, you must adjust for inflation.
Note that you are saying that the lift ticket price from 1975 to 1985 was increasing faster than it was today, which may be true in nominal dollars, but NOT true in inflation adjusted (real) dollars. 1975 to 1985 was a period of markedly high inflation (5-15% annually), but post Volcker tightening the fed (and directly causing the 1980 recession in the process) inflation dropped to around 3% by the mid 1980's and has been largely stable since.
