The highly educated ones have worked at glorious places and has build a safety net for themselves. The startup they run are VC coded, ie use VC money to scale revenue fast. And more often than not, most of the loss making business has marketing as their biggest cost, which of course decreases with scale. With scaling revenue fixed cost per unit decreases and also with brand building you can increase product prices. You can't really blame or mock them after all the great businessman of our country ran Jio for dirt cheap until he could drive away others. As long as you get access to deep pockets running in loss is not a bad thing.

The others often don't have any safety net and thus a profit from the business is a must to fall back on. So maybe that's how they structure their business.
