Critical assessment of comparative general claim: Conservative think tanks
Provide a critical assessment of the following comparative general claim:
The increase in the number and support of conservative think tanks has been substantial since the mid-1970s. The American Enterprise had twelve resident thinkers when Jimmy Carter was elected; today it has forty-five. The Heritage Foundation has sprung from nothing to command an annual budget of $11 million. The budget of the Center for Strategic and International Studies has grown from $975,000 ten years ago to $8.6 million today. Over a somewhat longer period the endowment of the Hoover Institution has increased from $2 million to $70 million.
