The electoral system in Italy: is it democracy ??

HOW ELECTORAL SYSTEM WORKS IN ITALY

A republic with a bicameral parliamentary system, Italy has a 630-seat Chamber of Deputies, the lower house, and a 315-seat Senate, the upper house. A government can stay in power only when it secures confidence from both houses, which enjoy equal powers.
A mixed electoral system was introduced in Italy beginning 1993 till 2005, allocating 75 percent of the seats under a majority system, with the remaining one quarter given by proportional representation (PR).
Under the majority, or plurality, system, the party garnering the most votes wins; under the PR, a party's number of seats in parliament is in proportion to the percentage of votes it won in elections.
In the parliamentary elections held on April 9-10, 2006, a full-blown PR electoral system replaced the mixed one. Each elector casts one vote for a closed party list, from which electors cannot choose individual candidates.
The main flaw of the current proportional representation system is that it produces highly fragmented parliaments and unsteady coalitions in government. For example, between 1945 and 1993 when the PR system prevailed, Italy saw a total of 52 governments come and go, with each cabinet lasting less than one year on average into their five-year term.

I think this all is quite a shame....some politicians are struggling to change this electoral law....but until the ruling class who has ruled Italy since (and before) the period called "the second Republic" (in the 90s )will not pass the baton to a new policic system (think that most of Italian politicians are over 60 years old ) the problem , and even the crisis afflicting Italy , will not be solved at all.

Nowadays Italy is ruled by a caretaker government.
