It totally makes sense for England to have the Plutocracy idea set, and will almost certainly be intentional.
I mean, look at the ideas:
Code:
plutocracy_ideas = {
category = MIL
bonus = {
technology_cost = -0.1
}
trigger = {
NOT = { government = monarchy }
NOT = { government = noble_republic }
NOT = { government = theocratic_government }
NOT = { government = papal_government }
}
tradition_of_payment = {
possible_mercenaries = 0.50
}
abolished_serfdom = {
land_morale = 0.25
}
bill_of_rights = {
global_revolt_risk = -1
}
free_merchants = {
merchants = 1
}
free_subjects = {
production_efficiency = 0.2
}
humanist_tolerance = {
tolerance_heathen = 2
}
emancipation = {
manpower_recovery_speed = 0.2
}
}
Abolition of serfdom, a Bill of Rights, Humanism, general 'Protestant' bonuses to trade/production... they all seem to fit. England has a tradition of balancing monarchy with a degree of republican ethos, and its aristocracy was curtailed at the expense of the peasant and merchant classes in a way that simply didn't happen in countries like France, Austria and Russia. Hell, the exact opposite happened there.
To me, it seems fine for countries like England and Holland to get this idea set. Presumably the alternative is the Aristocracy set, which really doesn't suit them at all...
