Man, a test league might not help them make money easily. While, the general perception being that the Saudis are uber rich and they wouldn't care about budgets is partially true, I fail to see why they would jump in and promote a Test league- where a majority of the 1st choice players might not play. With an already crowded international calendar, a test league will take up a lot of time and might only see national discards forming a part of the same.
With the subcontinental diaspora being huge in the Middle East, the Saudis would ideally want to pull cricket towards them. Saudi has been making some great strides recently in terms of relaxing norms, showcasing themselves as an open economy/more liberal. Cricket could be used as a pre-cursor to the FIFA 2034 they would be hosting. Gives them a decade to tamper and show to the world they are ready to host and welcome. It is akin to Mandela's South Africa using the Rugby World Cup hosting rights in the early 1990s to gain traction among the world's population/ to show the world that they are welcoming / open country.
I should have clarified that making money from a limited overs cricket league is easier than making money from a Test match cricket league.
Come on now- players from ECB, CA and BCCI are still miles ahead of their counterparts in BD, WI, SL, Pak to an extent. The main issue is that test cricket is fading in these lesser nations as there is little joy to be gained from getting beaten/ no hopes for winning the WTC. The tests you are alluding to is a mere handful just to prove your point.
I believe you are speaking for yourself here. The general perception has definitely changed over the years. T20/limited overs will attract audiences-you really feel if the IPL switches to a Test format, it will become a talking point? It will lose most of the brand value that it has built up over the years.
Using sports to wash away wrong doing- it is exactly what SA did in the 1990s by hosting the Rugby World Cup. Sports brings people together- so I really dunno why this term has to be used.
Very limited audience, not scalable, not profitable from a franchisee owner's POV. While you've mentioned the intention behind such an idea isnt to make any profit- if that is the case, why would anyone jump into it? Unless, ofcourse they were SLC or BCB
