Five percent

Five percent

What is 5%?

Well apart from being a proportion, here are a few things.

  • 5% is one in twenty
  • 5% is an arbitrary threshold value considered significant in statistical analyses
  • 5% is half the current rate of GST in Australia
  • 5% is a pay rise almost worth having
  • 5% is less than the percentage increase in US military spend under the Trump administration

5% is quite the conundrum. It is not very big and yet it can be big enough to be noticed. You would not want food prices to increase by 5% but they have, roughly every two years or so in most mature economies.

You’d like a 5% pay rise over no pay rise at all but in the US rust belt, many workers have waited over a decade to get it, only for it not to really matter that much.

It seems that 5% is an awkward, niggly kind of proportion. Always a bit on the cusp of significance — one in twenty is surely just chance. Give me one in a hundred and I’m listening.

The other day a friend of mine, also a fellow science nerd, told me that 5% of the hip pocket dollar is spent on the environment.

One in twenty of the dollars in the average wallet ends up as an environmental expenditure.

Now this bald statement that could take a bit of unpacking. What’s in the hip pocket? What is the environment in this context? Would the 5% spend include food or the council waste levy or just donations to the WWF?

In most of the developed world food counts for around 8% of household spend. There is an environmental levy in my own local council but I pay that in my rates, part of my tax spend. And my hip pocket has a whole heap of unavoidable bills from utilities to the mortgage.

We could be here all day figuring it out, so let’s just say that, on average, people spend 5% of their after-tax dollar on something environmental.

That’s $5 for every $100 that arrives in their bank account, at their discretion.

So is this enough? Is it significant?

People die if they don’t eat and have access to clean water. They need somewhere safe to stay and the opportunity to build a meaningful life with some fun in it. These primary needs would use up most of the $100, most of the time.

Add in the inevitable unexpected cost when the boiler bursts, the roof leaks or a family member needs hospital care and there may rarely be 5% left over.

$5 is significant if the cost of living has already allocated the contents of your hip pocket to the necessities of life.

This is where the thought usually stops.

The cost of living is unavoidable. If it eats up all you can earn, then the environment is not even a thought.

Only think a little longer. The environment is where the food, clean water, timber for the house, sand for the mortar, clean air, space for fun, among many other key necessities comes from.

Ignore the environment and it is used up, polluted and dysfunctional for these key goods and services.

Fail to pay anything for these things and they stop.

We should be very scared that we spend only 5% for there is no point in investing in ourselves if the foundation for many of the vital things we need is eroding away beneath us.
