Capital vs Humans, the EPP, PES, ELDR way?

According to the Guardian today, "EU executive considers reimposing border controls" (please read the article then my comments).

Is it a coincidence that all 3 key players in this, ie Sarkozy, Berlusconi & Barroso are all from the EPP European political party? The party that takes public pride in having 15 or 16 of the 27 heads of state/government as its members?

That via its majority in the European Council and the European Parliament has EPP members in all 3 top EU positions, at present, ie:

1) Presidency of the European Commission (where a majority of the Commissioners were proposed by EPP member parties/leaders in government)?

2) Presidency of the European Council (where again it has a majority, ie among the heads of state/government of the 27)

3) Presidency of the European Parliament (where its national members hold a total of 265 seats out of 736, the biggest and thus most influential group in the EP, eg as a result the EP's current President is from the EPP ).

I) Is the change considered by the Commission's President to Schengen in line with "EPP values"? In line with European values?

II) What is the real value or use of the European political parties and political groups thereof in the EU policy making? In European integration?

IMO, the EPP has to prove its EU "values" in the Schengen issue since the parties involved, ie Sarkozy, Berlusconi and Barroso are EPP.

But that "burden" is not only for the EPP.

IMO, the EPP, the ELDR and the PES have to adopt clear positions on issues such as Schengen, Immigration, etc, that both reflect & bind all their member national parties and leaders. Otherwise, what is their real use when compared eg with more generic (and less binding) international groupings such as the Socialist International etc?

In other words, when the going gets tough, the tough get going, thus the EPP and other key EUropean political parties have to show their mettle in these hard and crucial times.
