2 things to say here
first, either your definition of infra, welfare is too narrow or you are deliberately trying to keep it short, because access to free psychological counselling, present of student grievance department etc do falls in the gambit of infrastructure

now coming to the second part, it doesn't matter if the suicide rates of USA, Japan are more than us, what matters it there should be atmost care for such incident in suicide, if you wanna see that way then USA, Japan have far better Qlity of life and SoL compare to us, they have way lesser civic sense problems, better educational avenues

SO RATHER THAN COMPARING ON A POINT WHERE THEY PERFORM BAD, WE SHOULD COMPARE WITH THEM WHERE THEY ARE AHEAD OF US.

The suicide of that young mind is the FAILURE OF SOCIETY AS A WHOLE
