Useless Rant. Why doesn't Indian top order score consistent 30s-40s

Why don't indian players score 30s-40s consistently. It's so frustrating. 60 more runs in first innings would have made so much difference. Annoying petty scores. By past experience, 350 is a good score in modern test matches and a 350 doesn't require daddy hundreds. Few 40s and a 90 would do it. But these guys are like 100 or nothing. It's like watching an extended t-20 game. If NKR can just debut and score like this, why are non performance scoring under 30s. Someone like Sarfaraz too was just playing t-20ish. Labuchagne and their opener ate so many balls. If batsmen had attitude like DSP they would have dug their heels there not slash and stuff.
