National teams or League Clubs?

So the question speaks for itself. In a federation, which of both should have a higher priority? To expose both points of view, please think of this:
Your national team is about to get eliminated from the next World Cup. You know that if your team loses the World Cup, lots of money inverted in sponsors, kit makers, salaries, image, etc, will be wasted. 
So the best solution is: get the best players (usually from your local league), make a powerful national team and qualify to the World Cup final stage.
However, who cares about the local league?
Any team could become champion and key players should participate in the National team instead of participating in the local league, because their HIGH level of skill makes them deserve to play in the National team instead of the mediocre local league.
So the National team is definitely more important than the local league.... ???
Now think of this: 
Entrepreneurs of the country, spending millions on transfers for the club to work well.
The club actually IS working well, after years of bad results different club managers and players.
Congratulations! You did a great job, you deserve a great campaign, lots of money in sponsors because you are actually the sensation this year. Maybe a title.
BUT WAIT!!
The National team is going really bad, they need help and they want your players.
What about taking your goalkeeper, two defenders, a pair of midfilders and of course, your striker that scores the goals?
Who cares if your club gets dismantled?
The important thing is that THE NATIONAL TEAM IS GOING TO THE WORLD CUP!!
So bad results return, you lose the league, your aspirations you had when you were playing well, your players (who are obviously good) get seen by the whole world and now "x" team in Europe wants them and they leave.
To this now comes the question... what is bad with this? It's what happens here in Mexico...
So now think of the new, young talented players in Mexico. Will they want to play here, in a mediocre league? 
*mhm*Pulido*mhm*Corona*mhm*.
They will obviously leave the country for better oportunities.
And now the current champion in the league exchanges players with the team that gets relegated. 
Players that play well end up in the second division. 
Few players have THE GREAT OPORTUNITY OF WARMING UP BENCHES IN EUROPE.
So really, ask yourself the question, is your national federation focused on the sport in your country (a competitive league, good players, new talents, players sold to Europe to PLAY and for millions)?
Or is it focused on money and image (have you seen the new Mexico jersey? They will win Copa America with it! They will play the cup with the second team formed by MEXICAN LEAGUE PLAYERS)?
And you? Who do you think should keep the best players? National teams or League Clubs?
Think of Europe national teams, with some old players, respecting the club interests and local leagues so they don't interfere with their destiny (championship, money, fans, sponsors, money for more players).

Just a video I found of the importance and value of a National team.
