No it is not a good point. That is just equivalent to opting to play for South Australian Redbacks rather than the Kochi Tuskers because the Redbacks pay substantially more.
Representing one's country, in any field, is a completely different matter altogether. There are enough examples for that, in India, all over the world. For instance, a supreme court judge would earn much more in private practice, the US secretary of state takes a cut in earnings, and so forth. I agree that people choose what rewards them more; but those rewards could be things like pride, self-satisfaction, respect, honour etc., not just money. Heck, even hard-nosed businesses splurge on 'prestige advertising'. The Bharat Ratna, the Nobel Prize or the Oscar is not fiercely coveted because of the monetary part associated with the award.
