The metaphor of the crowded Luas

Yesterday I travelled by Luas from Dublin's Milltown to Harcourt Street. It was morning rush hour and the trams were filled to capacity. People were packed together around the doors.
It was impossible to board the tram.

The next one came within seconds. It too was crowded but there was some room. Again, people were packed around the door areas. But down the aisle it was clear to see that people could move closer together so as to allow more people to board. But no-one said a word. They simply allowed it be so.

Something about the Irish, we take so much, say nothing and then when we go home, or in our own private space criticise.

Is that part of the reason why the IMF are about to board a Lufthansa service from Frankfurt-am-Main to Dublin?
