To revert to the question of taxation.
MOnica is constantly asking for a definition of wealthy. So I went back to Thomas Pikety.
Firstly, it is difficult to put a monetary value on 'wealth' and Pikety doesn't attempt to do that apart from using monetary values to illustrate some of his points. What he does do is to look at wealth in the context of shares of 'national income'.
He defines national income as being similar to GDP, the monetary value of all national outputs, but he modifies it slightly by allowing for depreciation of the capital goods involved in production, e.g plant, machinery,and infrastructure. He then estimates that national income in developed countries equals about 90% of GDP.
It is possible to break the share of national income into labour share and capital share but it's complex because the two overlap in many individuals so, apart from noting that it frequently works out at about a 70/30 labour/capital split it isn't a particularly useful tool for analysis.
He therefore looks at the ratio of capital (wealth) to income in terms of the number of years worth of national income a figure will represent.
e.g. If the per capita net income (i.e share of national income) is £30 - 35,000 and private capital wealth is £150 - 200,000 then private wealth equals 5 or 6 years worth of national income.
This is just an average. Naturally there is a huge variation between individuals. Some will have little or no capital wealth and some will have far in excess of the 'per capita' amount.
Pikety finds that the distribution of wealth between holders of capital wealth is concentrated in the upper percentiles of wealth holders. He found that in the countries whose data he used for analysis the top 10% of capital holders always owned more than 50% of all wealth.
Conversely, distribution isa bit more equal between holders of labour income, where the upper 10% receives 25 -30% of the total labour income and the bottom 50% gets 25 -33%. Whereas the bottom 50% of holders of capital income get only 5%.
Without putting any figures on it this tells us that there is a huge amount of wealth being held in the UK by very few people, wealth which it could be perfectly proper and equitable to tax without having to tax those who hold far, far less.
When we start discussing wealth on this forum it always seems to descend to recitations of personal situations and personal desire to protect what wealth people have. If looked at in terms of wealth distribution in the UK we can see that most of us are paddling in the shallows of the pool of wealth, fighting over amounts that would be considered paltry by extreme wealth holders who are way out into the deep end. But many are not happy with the concept of taxing wealth and defend those who some of us find to be indefensible because, it seems, they themselves fear for those relatively amounts that they hold.
There is, of course, an ethical and ideological dimension to all this in that approval or disapproval of wealth taxation depends very much on individual's view of the function of government and their economic ideology.
P.S Pikety used a wide range of 'developed' countries in his research, including the US, the UK, France, Japan, Canada, Spain, Germany and more..... His findings are not UK centric.
