And those people should still get a shot at life. There are buttloads of actual successful people who started from literal crap.
I think you underestimate how miserable the average person is.
Most people — believing they are normal, reasonable, and typical — tend to assume they are representative of the majority and project their thoughts and feelings onto the majority, which is often incorrect.
I wouldn’t presume to tell someone with a shitty life that they’re better off not even having the opportunity to improve it.
