Poland (and most of Eastern Europe) has been steamrolled repeatedly by neighboring empires which have imposed what amounted to foreign governments. These governments ruled despite, not due to, the local populations. Ergo secret police, network of informants, etc, just to control the population.

It's hard to have very high trust levels when your own government and state are working against you and when your coworkers and neighbors can at any time rat you out for unpatriotic activities.
