I don't fully agree because there are still some different thoughts in assessing why players prefer to play in a league that is more dominant in getting money than a career.
The fact is players go for money and that is just it. Just that their career in the process is also intertwined with money and of course success. The simple way to know this is that is there is no more money in sport today, you will not see those players working hard to play for their country and aiming to get knto one of the bet clubs in the world. Everything is about money.
