In majors dream he critiezies humans.what are the reasons that he doesn't like man?

From the text:

There, comrades, is the answer to all our
problems. It is summed up in a single word--Man. Man is the only real
enemy we have. Remove Man from the scene, and the root cause of hunger and
overwork is abolished for ever.

"Man is the only creature that consumes without producing. He does not
give milk, he does not lay eggs, he is too weak to pull the plough, he
cannot run fast enough to catch rabbits. Yet he is lord of all the
animals. He sets them to work, he gives back to them the bare minimum that
will prevent them from starving, and the rest he keeps for himself. Our
labour tills the soil, our dung fertilises it, and yet there is not one of
us that owns more than his bare skin. You cows that I see before me, how
many thousands of gallons of milk have you given during this last year?
And what has happened to that milk which should have been breeding up
sturdy calves? Every drop of it has gone down the throats of our enemies.
And you hens, how many eggs have you laid in this last year, and how many
of those eggs ever hatched into chickens? The rest have all gone to market
to bring in money for Jones and his men. And you, Clover, where are those
four foals you bore, who should have been the support and pleasure of your
old age? Each was sold at a year old--you will never see one of them
again. In return for your four confinements and all your labour in the
fields, what have you ever had except your bare rations and a stall?
