How many outcastes did you have as friends in school/college/workplace? Im sure none. Cause none would want to make friends. When your brethren get hitched isnt CASTE important?? Caste was never irreverent to Indians.
Indians will never prosper mentally and spiritually whether they are here or Abroad. Caste is a part and parcel of you. Cause thats the only thing you cant change in your life. You will die as you were born.
