It is an important question how far political change, which almost always involves some kind of conflict, also tends to be accomplished by violent means.

In the latter case every change tends to become a pay issue and another bureaucratic burden on the organization.

Local changes to the initial pattern tend to remain local.

Local changes to the initial pattern tend to spread indefinitely.

But other changes, especially economic ones, have tended to increase their dependence on their families.

People who make healthy changes to their life tend to get other benefits tag along for free, research has shown.

Substantive changes in either program tend to affect the other.

The changes tend to come two steps forward, one back.

Gradual or slow changes in vision tend to be less serious.

I actually take the view that technical change will tend to speed up liberalization in future.
