We all work. At work we have a boss. Your boss is higher than you and you are lower than your boss. Does this mean that your company is bad for making you lower than your boss? No. You are lower than your boss, because your boss deserves to be higher than you. He is better qualified and experienced and thus he deserves to be higher than you. You are less qualified and experienced and thus you deserve to be lower than your boss.
The Hindu caste system is exactly like this example.
There are lower and higher living beings. Animals are lower than Humans, within the animal kingdom there are higher and lower beings of animals. A horse is higher than a donkey. A snake is lower than a dog, a bird is higher than a fish etc.. Every living being is a soul covered by a particular material body depending on what the soul deserves. This is based on the karmic actions taken by the soul in previous lives. Thus a soul may occupy the body of a human today but in his next incarnation he may take up the body of a donkey. A person may be born in a rich family in this life but in his next life, he may be born in poor family. Some people are born to poor families due to bad karma and some are born to rich families due to their good karma. The rich person is higher than a poor person etc..
