Let us take an example.
The livelihood of someone who works in a factory producing widgets depends on the amount of widgets being produced finding enough of a market to create a profit for the employers so that they can continue employing them.
The price of the raw materials for Widgets goes up because a/ the government taxes widgets in an attempt to curb the growing toxic used widget mountain that they have agreed with the EU and UN to reduce and b/ a natural disaster in the country that is a main supplier of widget raw materials pushes up the price.
Would said widget workers be justified in downing tools and blocking imports of widget raw materials, bringing the country to a halt, to pressurise the govt to drop widget tax? Or should they pressure their own employers to diversify away from widgets to secure their long term employment given that the widget tax is a signal that governments (supported by a large section of the population) want to find alternatives to widgets?
As for self employed widget makers? Surely key skills for self employment are the ability to be flexible, to know when to get out of a particular sector, to be prepared to move with the times and changing markets? Are people to put their sectional producer interest before the need of people not to be poisoned by the toxic widget mountains? Will a romantic view of these groups as "salt of the earth" traditional male workers blind the left to the basicly anti-progressive nature of their position?
As for people in isolated areas who
really need cheap widgets to live due to lack of access to post widget technology, are this small minority to define policy for the whole country? Perhaps they should organise collectively to demand post widget technology be more available in their area, or ordinary widgets be specially subsidised for them. Or perhaps they should organise at work to get a pay increase to keep up with the cost of living?
In the long term of course, the logic of the market is that a country that sticks with outdated widget technology due to political cowardice will end up with having its' widget factories go bust anyhow as the widget raw material runs out and other countries steal the lead on post widget technology.
Of course it could be argued that there is no need to curb widgets, they are not poisonous and the government is just using them to raise "stealth taxes", but then you might be accused of donning a tinfoil hat and joining the conspiraloons............
