GDP is of relevance to everyone, the fact you don't understand it does not change anything. GDP is a measure of the size of the economy, and if the economy is growing then that means there is more money in it. You're correct that that does not mean that as soon as the economy grows people will see instant benefit from it, levels of inflation play in too and companies will not start handing out pay rises left and right the second the economy shows signs of growth, so yes you can see GDP go up, but no people wont instantly see benefit.
I don't know why you say Ireland has a high GDP, no it doesn't, it has a smaller GDP than countries like Iraq, Kazakhstan, and Pakistan, maybe you meant GDP per capita? If you want to know why Ireland's GDP per capita is high but the people aren't seeing the benefit of it then it's simple- Ireland is a tax haven and like all tax havens they have a high GDP per capita, there's a reason Apple has many tens of billions sat in banks there - it's a low tax regime, but that money sat in banks isn't in the real economy, it doesn't feed down to employees because it's being held in banks simply for the purpose of being kept off shore. This is the price of running your country as a tax haven, you get a lot of income, but it wont be productive money for the economy - it wont be used to pay higher wages or any such thing. The UK is not a tax haven so is not in even a remotely similar situation.
What we have in the UK is healthy growth because it's sustained, and the fact it's sustained means companies can start increasing wages, and guess what? contrary to your parroting of now obsolete memes that's exactly what's happening. Throughout last year wage rises started to track with inflation, and through this year they've finally started outpacing inflation.
Yes there have been big issues with zero hours contracts and self-employment over the last few years, and this has been key in Carney not increasing the bank of England's base rate, but as bank of England minutes have shown over this last year it's now clear that even that trend is in decline- those zero hours contracts, and that self employment is now being replaced by real sustained employment. It's for this reason that a rate rise now looks likely next year, instead of in 2016/2017 as originally planned. I suggest you catch up on this years monthly BoE meeting minutes if you want to get an updated view of the situation of the healthiness of employment in the UK rather than the outdated view you currently hold.
The things you cite were true a year ago or just over, but in the last year it's become clear that this is real growth and as a result even salaries are increasing (they're certainly not decreasing as you claim- go check the ONS stats on the issue, or see here for example: http://www.theguardian.com/bus... - this is from April just as above inflation wage growth started, the pace has improved even more since then).
So I hate to say it but your whole argument is wrong, it's based on a lack of understanding of economics on a national level, it's based on a naive belief that improvement should be instant, and it's based on a simple lack of knowledge about what the underlying trends actually are in our economy.
Our GDP is growing, our wage rises are outpacing inflation, zero hours contracts are no longer growing, debts are not soaring, bailiffs are not doing record business. That's what I consider healthy growth- you're right, your theorised claims would not be healthy growth but they're not what's actually happening in the country right now, they stopped being true at least a year ago, your information is now completely out of date and incorrect.

I purposely left food banks out of that last paragraph above because their use has been growing even in the boom times before the recession, turns out if you offer free food with no checks, balances, and means testing that people will take it so drastic rise in their use has been occurring regardless of the economic weather:
Hence sure crying "but food banks!" sounds good, until you realise that whilst we can theorise that food banks are going to see an increase in visitors in times of poor economic performance we still see increase in their usage in times of good economic performance and so it's incorrect to assume that increase in food bank useage correlates purely with poor economic performance - clearly it doesn't because we can see it rising in boom times.
I suspect we both know what healthy growth is, the difference is I know what the underlying state of the economy is because I've bothered to research it, you however are claiming it's unhealthy based on outright falsehoods.
