The point is, the Indian system is tough because of competition and when you get early success then you have to perform consistently for the next 10-15 tests as well otherwise someone else will replace you.
This is one of the reasons why more and more cricketers are shifting their time and resources to the T20 format since they stand to earn more money and popularity in a way shorter period without worrying too much about other factors.
Honestly, I would do the same because time is money. Test cricket is great for several reasons, but it requires a huge time+effort investment.
I have to talk about few things with current system is good but if we have centralization then surely things can go better and improved because as currently we are having money in Indian cricket if Government of India give them status of industry it's also going to be fruitful as they will be able to have more benefit and also helpful for the many other sports associations as well there is too much money in this game and now every youngster having dream of playing into IPL, but this all is not possible so they need to work on domestic setup and bring good competitions with too many teams which will be also having enough money and competitiveness.
Ranji Trophy and IPL are going to be trademarked for the domestic leagues and also going to have huge investments as well which will allow BCCI to manage things and have strong structure and stadiums as well.
