Just because Rama says the disappearance of caste system is equivalent to decay in humanity, I personally won't change my opinion that caste system is bad.
I think the plight of women and the vast majority of masses has been improving since the so called treta yuga. Things were better for more people in Mahabharatha which happened later than Ramayana. A man like Karna being accepted as a king in Rama's period would have been a pipe dream, the less said about women the better.
As for looting, I think there was more looting earlier during Rama's period and earlier king's period than now. With the vast majority paying for the comfort of the few. Things are now a lot better. Irreligious feeling also doesn't equate to being bad, as long as we are good to each other.
