Because no matter how corrupt & powerful the ruling class is. They're powerless in your personal decision of childbirth. They simply cannot procreate on your behalf & also cannot physically force you to have kids. So once again I repeat you're not really angry enough with the situation if you're still having kids. Because you having kids simply means you're okay with this system & you vote in favour of the system by allowing it to continue by creating one more person to continue this system.
