Are those who die without someone praying for their souls , compensated?

Month of November is dedicated to the deceased faithful. One of the Mass Intentions of Catholic Church for the month is to pray for those souls who have no one praying for them. That implies that those who die without relatives or friends to pray for them post- death, are in a disadvantageous position vis- a-vis those who have many. My question is: According to Catholic Church, how does God compensate those who die without relatives or friends to pray for their souls ?
