All evidence is that other European nations were a bit annoyed that the Irish government set it so low. It was an incentive for multinationals to locate their European operations in Ireland rather than another European country, and the other countries saw it as producing a 'race to the bottom'. For instance, France and Germany recently asked Ireland to raise its corporate tax rate, but Ireland refused:
Ireland takes hardline stance on corporation tax as bailout talks begin
Dublin tells EU and IMF that lowest rate in any major European economy is 'non-negotiable'
A defiant Ireland tonight insisted its corporate tax regime was an "absolute red line" as it took a hard-line stance in the opening skirmishes with Europe and Washington over a possible bailout.
On the day a dozen officials from the International Monetary Fund descended on the Irish capital, finance minister Brian Lenihan said the country would not surrender its investment-friendly tax regime as the Washington financial experts began their health check on the economy.
Prompting speculation that no quick deal was in prospect, the government sought to allay mounting public fears that Ireland would cede to demands from Germany and France to raise its 12.5% corporation tax – the lowest of any major European economy – as the price of a bailout.
Comments earlier in the day by French economy minister Christine Lagarde that the negotiations included a change to the tax regime had promoted an immediate backlash in Dublin. Deputy prime minister Mary Coughlan told the Irish parliament that the low rate of tax was "non-negotiable" even though the government conceded that it may need help to deal with what Lenihan called the "very big issues" in its debt-laden banking system.

For instance, it had the second highest minimum wage in the EU by normal exchange rates las year, and sixth highest when the cost of living is taken into account (notice that this means Ireland was a high wage country, but expensive to live in):
Eurostat tracked the minimum wage of 20 EU member states in January 2009. When looked at in monetary terms only, Ireland has the second highest, with recipients being paid €1,462 a month. This compares with €1,642 in Luxembourg, €1,321 in France, and €1,010 in the UK.
When expressed in purchasing power, the gap between the countries narrows considerably. Ireland’s minimum wage is reduced to €1,152 per month, just €2 less than that of the UK’s monthly payment of €1,154. In France, the purchasing power of the minimum wage is €1,189, in Belgium it’s €1,254, the Netherlands pay €1,336 and Luxembourg continues to top the table at €1,413.

So there may be future low wages. But this is a result of the Irish governments' policies (eg guaranteeing the banks' debts).
