From what I saw on the news, Canada is going to suffer from Americans not buying their cars. Ok, so stop building cars, and build something else instead. Train the workers for a new industry.
What I would like to see is a pivot away from consumption. We don't need new models of cars and phones every year. Innovation doesn't occur at a rapid enough pace to warrant that and such a rapid product cycle encourages a disposability culture.
Things should be designed with serviceability in mind and alot of improvements to a design can be offered as retrofits or upgrade kits instead. This could be better for the environment and cost effective for those who want or need it.
But the system isn't designed in such a way to encourage that. People vote with their wallets and they've shown that they want to buy(lease) throwaway products every year, not take care of them and then chuck them when the next one's released. Companies are happy to oblige.
Everyone complains about shoddy work for fabricating houses for example, so get the workers to train up and help in that industry. This will provide more workers for the needed industries, and the quality of the new product will improve.
I think part of this is the problem of capitalism alluded to above which is that it's driven by units sold, products consumed, rather than the quality or other traits of the product.
The faster they slap a unit together, the faster they can sell it, and the more profit is made per unit of time and money. Quality suffers but even if it falls apart after 10 or 20 years, it's fine, the sellers will be long gone by then or they can hide behind plausible deniability.
And that's another thing, that alot of people/companies just don't care how their actions affect others down the line. Another symptom of misplaced priorities. Reducing costs and expanding margins for the manufacture and sale of a product, without regard for the families that will live with the consequences of the corners cut.
It's not so much the workers fabricating the design, it's the companies designing and selling them. Generic designs that are made to a purpose(profit) and check out on paper, but don't hold up to real world stressors.
Building a home should mean building and providing the means for a legacy, not producing a real estate commodity.
Anyway, enough ranting and raving. That's just the system we live in, what can you really do about it?
