This is what happens when economic development selects quantity over quality. And IMO it's the right choice, especially for large countries. Nevermind not being able to pay for for quality in the first place (lack of qualified skill), when you're at the bottom of the ladder it's long term better to trade safety/lives for more/faster progress. The aggregate societal and human gains that can be afforded from growing income almost always trumps loss from chabuduo. Especially for large countries like India and PRC with so much (bluntly) disposable bodies, you want to throw everyone into the mixer because with that many bodies, it's important to seperate wheat from chaff in terms of human capita as soon as possible and harness them - otherwise potential gets squandered on massive scale. It's not just construction. It's important to manufacture lots of things because even if you make lots of shit, you'll also discover the great makers who makes things that are internationally competitive. Or spam lots of academic papers, because even if most of is hack fraud, it's also maximizing for gems that raise ceiling on top end. Countries grow by learning and improving via doing a lot, even if most of it is not good.
