1980s is a post-expansion, pre-internationalization era.
21 teams with vast majority of talent coming from one country, a diluted talent pool.
Completely disagree.
Everything from 1967-68 onward is "post-expansion", of course, but the 1980s is
not a particularly expansion-affected, or talent-depleted, period. There were 32 pro-hockey teams in 1975, and there were 21 (a 34%) reduction) from 1979-80 onwards. Coinciding with this reduction was the increase in European and American players.

With the exception of the last 6 or 7 Americans listed above, all of these players were active by the
mid-1980s, if not much earlier (some in the 1970s). These include many of the best players of the whole era.
Bear in mind that a 21-team League had about 275 fewer jobs available to NHL players than the League of today.
Add to that the fact that this was still a "flop around like a fish out of water" goaltending era and "big, physical hitters" defenders who skated as if on sand, and you have video game numbers.
"Video game number" has become such a cliche for people who weren't there that I think these people are actually starting to believe it.
Scoring in the 1980s, in general, was higher than NHL historical averages but not by huge proportions. Goalies then stopped close to 90% of shots and goalies today (with vastly easier-to-play-in-equipment) stop about 90% of shots.
And you may have noticed that scoring has been increasing in the past few years.
For example,
2019-20's leading scorers (projected a bit to 80 games):
124 - Draisaitl
121 - McDavid
110 - Panarin
109 - Pastrnack
108 - MacKinnon
100 - Kucherov
99 - Marchand
96 - Kane
96 - Matthews
92 - Eichel
...compared to 1986-87:
183 - Gretzky
107 - Kurri
107 - Lemieux
107 - Messier
105 - Gilmour
103 - Ciccarelli
100 - Hawerchuk
96 - Goulet
95 - Bourque
95 - Kerr
shows us that some seasons in the 1980s are very comparable to today's leading scorers at the all-star level.
Point being: You can dislike the 1980s' game as much as you like, but the argument that it was a one-country League or that it was talent-depleted simply doesn't hold water.
(In my own opinion, the League today is slightly more talent-depleted than the late 1980s was, with the ideal "talent-to-teams" ratios being around the 1950s and the late-1980s/early-1990s.)
