That is a well rounded answer Rhythm Thief, however economics are the answer to your question.
I referred to it earlier as madness, but it is what it is, we go to work for money in return for services provided. We spend some of that money on services and goods that we and others like us provide. It’s a circle of sorts, we are given something (money) which we swap for something (goods and services) in the old days before money we were given, say three bags of carrots and a bag of apples, which we swapped for other things, so this concept has been around for some time.
Now nobody wanted a monopoly on carrots and apples, but money is a different story. 99% of the world’s money is ‘owned’ by 1% of the world’s population. People like Beckham or Schumacher are not in that 1%, they may have millions, but it only puts them at the top of the 99% with SFA, so to speak.
The 1% do not want to share their fortunes, so they pay us just enough to buy the products and services they provide, they also allow a Beckham or Schumacher to ‘succeed’ to drive us 99% to work harder.
So what has this got to do with drivers hours I hear you ask.
Simple, if we work less, we earn less, so we buy less. Hold on I hear you say, extra drivers will be required, so the balance is restored and to a point it would be, except it would require devaluation of things as current prices would be too high. The volumes would compensate though.
Now you’re saying I’m talking out of my arse, a few thousand lorry drivers won’t make a difference to the world economy and you would be correct, except for one thing. Government!
Government has no money, except from taxes, lower wages mean less tax, ok so more drivers means more tax, so it balances, but it doesn’t because of tax thresholds, we all earn a certain amount before being taxed, so more money will be untaxed.
Do you think the government will spend any less? They won’t, so they’ll increase taxes on those that are higher paid, this has a double effect, one it reduces their spending power and two it removes the incentive for them to work, what starts with lorry drivers will spread into other industries and the economy will crash.
This will ■■■■ off the 1% and they’ll instruct their puppet governments to do something to rectify the situation so that their pots of gold continue to be filled from the fruit’s of our labour.
Long story, but the short answer is…get used to 60hrs a week as it won’t be changing until robots replace lorry drivers!
I rarely do more than 10 hours but I want the option to should I choose. Mostly to cover rare delays or road closures. I’d rather use 15 to get home than get stuck on a night out
