Well, the 'potato famine' in Ireland wasn't just due to potato blight. The English were ripping heaps of food out of the island. Given that the population of Ireland halved as a result, it seems much of a muchness to me when playing 'oppression olympics' about who had it worse.
Remember also that the English didn't conquer India just with their own armies. They used allies and puppets; England didn't have the sheer manpower it'd take to conquer India alone. Basically their tactic was find a small power and give them advanced weapons. The small power then enjoys becoming a big power... but is then dependent on England for the arms supply, and so becomes a puppet. The English were very good at politics, playing people off each other.
