The biggest issue with our environment that drives these problems is that human brains can only reliably grok a few hundred other humans as being people. Beyond that, to a greater or lesser degree, anyone else just feels like an object (which is why we feel upset when people we know die but the statistics of how many people die each day globally don’t have a similar effect.)
Some of us cope better than others but fundamentally any environment that requires humans to be reliant on interacting with over a few hundred other people will lead to people treating each other as objects.
It’s why conservative people often feel it would be inconceivable to mistreat someone they personally know but will casually do profoundly cruel things to people they don’t. If you view their actions towards people outside of their sphere of personhood through the lense of what is and isn’t an appropriate way to treat an object rather than a person they often seem perfectly naturally.
