There was a huge change elections in 2015 but now the situation in Poland is quite complicated. On the one hand, the country is continuously improving and on the other there are serious tensions.
The complication is the result of changes pushed by the current government. Changes are quite revolutionary and refer to many areas of social and economic life. For a full understanding of this situation, it is important to observe how public debate is structured. The fundamental aim of the United Right (coalition led by PiS) is the far-reaching change of the political and social system in Poland, including at least partial exchange of social elites. The result of this approach is the middle-class anxiety about its position and its opposition to the planned changes. The government sets the elites (which also include certain middle-class groups) against the lower class, which position is improving due the welfare as well as dignity policy.
Therefore, apart from the growing political conflict on the ruling-opposition axis, there arises social conflict (also on economic basis) between elites and masses, or more precisely between lower and middle class.
As a result of this policy, the ruling coalition gains the support of the lower classes by building a large (though uncertain) electoral base and there is no chance for opposition to attract those voters.
