Many people have made the calculation that it is better to work part time or stay in lower paid (less strenuous and stressful jobs) because the tax and welfare system does not reward them for working more . . . Therefore people on middle incomes are paying higher tax relative to everything else than they would have 2 decades ago and more than their European compatriots.
Is it any wonder then that nurses builders and labourers have decided not to work 40 hours or more , or do unsociable hours etc because they are not rewarded by our "progressive " taxation system.
The problem with this theory is that the distribution of household income in Ireland, after tax and transfer payments, is about average for Europe.
Yes, we have a more-than-averagely progressive tax system. But we also have a more-than-averagely skewed wage structure — i.e. a greater gap bewteen the top and bottom earners, before tax and transfer payments, than is normal. The one offsets the other, and the combined effect of the two is that the distribution of household disposable income in Ireland is close to the European average.
Which in turn means that, if you work longer hours/take a more senior or more skilled job/whatever, even after paying tax, etc, you improve your material circumstances in Ireland about as much as the average European does.
So, if it's true that Irish people are less incentivised to work longer/harder/smarter than our European neighbours even though we get the same material reward for doing so, the reason may in fact be that we are less incentivised by material rewards than they are, which would be a cultural thing.
It's not impossible that that's the case. But it may not be. One of the premises of the argument is that Irish people do opt to limit their working hours, etc, more than in other European countries. Is this, in fact, true? I haven't seen any figures on this, one way or the other.
And, if it is true, we need to consider that factors other than the disincentivising effect of high marginal tax rates may be at work. For example, if Irish people opt to work part-time or to take career breaks, this may be partly attributable to the higher costs or poorer availabilty of childcare than is the case in other European countries. There'll be many other factors like this in play, and disentangling their effect may not be easy.
Finally, we need to consider the welfare/wealth distinction. A person who works longer hours may be richer, but not necessarily better off. Governments tend to be focussed on GDP and similar figures, so they always want to to work longer, smarter, etc and will adopt policies designed to get you to do this. But your own choices may be affected by a wider range of considerations — you may think you'll be happier and healthier if you have less stress, and more time with your family, or doing what you enjoy.
