We should be thankful the US doesn’t have a system like that which artificially reduces the supply of labor.
We should make it easier for people to work in the trades. Not wrap and bunch of unnecessary formality and regulation around it.
However it's likely to increase the overall level of training, which is good for someone who needs their broken trim board replaced.
Now when it comes to stuff like building a kitchen, you could go with proper carpenters or furniture folks or a handyman. It’s good to have those different categories and know what you would be getting.
If there is a large risk when work is low quality, there is regulation. The more possible danger, the more regulation. This is OK.
But an argument for regulation that is just some hand waving and repeating "standards" is not a legitimate position. It is an attempt to build some little bureaucratic empire which will enrich a group via regulatory capture.
The government wins as they now have more employees and more power and the people already in the trade win. Everyone else loses.
If you have to regulate industries institute a proficiency test and allow different levels of expertise. A plumber or electrician for home repair is a totally different level of complexity to one in industrial applications but it’s the same certification. The guy doing wiring in my house just does not need that level of education and I don’t really want to pay for it.
A typical handyman can’t and won’t touch anything that could actually cause harm (gas, plumbing, electrical) and poor quality work will result in a negative reviews and no repeat work for the handyman.
More opportunities for training and upskilling, yes!
But you should not start some unnecessary credentialing/licensing system that restricts the supply.
