Latvia is producing less quality players than before KHL time. Belarus is barely developing any talent at all. Kazakhstan = they have 1 players in the KHL who is actually a Kazakh. Czech and Slovakian talent either go to NA or Scandinavia. If a player is good enough to earn big money they won't join Lev or Slovan but go to NHL or teams like SKA, Ak Bars, Metallurg etc.
Medvescak? They have almost 100% imports in their lineup.
Donbass? No development of Ukrainian hockey at all. All Ukrainians on the roster either are veteran superstars or come from other youth programs.
I'm really not a fan of seeing KHL team as a cure for the country's hockey problems but your post is dramatic exaggeration where you went out full on to bash the KHL teams regardless of the facts. Most notably:
1) Latvia's hockey is living the years of resurrection, Jekimovs, Indrasis, Kenins, Freibergs, Gudlevskis, Girgensons, Rihards Bukarts, Jevpalovs, Lipsbergs, Kulda, Egle, Blugers, Golovkovs, Punnenovs, Mezlikins: this is 17-24 age group of absolutely high-end (by Latvian standards) Latvian prospects. There has never been that many. 7 of those guys are solid pros already, 5 are playing (and producing close to PPG) in CHL, 2 in NCAA and Egle is NCAA bound. There has never been so many. Pelss (R.I.P.) is missing from the group.
And that's not counting guys like Klavins, Roberts Bukarts, Mickevics, Kuzmenkovs, Upitis, Bicevskis, Pavlovs who will be solid NT players for Latvia but can't be treated as elite prospects because this froup is so deep.
Now I'm not gonna say KHL is responsible for this revival but it obviously didn't hurt and your words are just so, SO false.
2) Barys have one player who is
ethnically Kazakh. Kazakh hockey is in much, much better shape now than it was when KHL was created: the league is pretty good, 2 teams are rather successful in the VHL and Barys is doing well in the KHL icing mostly a Kazakh (Kazakh born and developed, at least) lineup. They even have few really solid prospects (Mikhailis, Koshelev, Savitsky, Sergiyenko, Zinchenko) and yes, ethnically those are Russians and Ukrainians but who is to blame for that and what difference does it make?
3) Yes Lev is an artificial club which really doesn't do much good but Czech hockey is also a bit bigger thing than what one KHL team can fix. Slovan, meanwhile, was there all along so nothing has changed from Extraliga days other that Slovak prospects have a chance to play in the KHL now. And obviously, the better a player the bigger contract he gets and for the richer team he plays, that's the nature of the business, what an existence of the KHL has to do with it?
4) Medvescak was established in the place where hockey pretty much doesn't exist so sure, KHL can't just magically fix that.
5) This is the first year they have an MHL team so obviously KHL pros on the roster are from other Ukrainian teams, it couldn't be any other way. And even though this was the first year they had the team they have a huge bright spot on that team - Lyalka will probably be the first Ukrainian drafted in years and now they can proudly say that he didn't need to leave Ukraine to be noticed. Something which had been impossible ever before.
