To add a point, licensing will shift the blame from corporations and their management to workers. This will mean that the blame won't be placed on management cheaping out on processes to ensure safety, but instead the 'bad apple' developer. This is bad for both consumers and workers.
Licensing in all industries, especially in medicine and law needs to be abolished ASAP. it has devastated many lives (it's too costly to get multiple opinions) and robbed the middle class in every town across America.
