~20% of workers in Europe are unionized. ~30% for Canada, ~10% for US. Canada's labour laws are very similar to US, only slightly better. It's not better than or even close to being as good as Europe.

This difference is coming from different culture and priorities. Lack of unions isn't why you don't have universal healthcare in the US and other such things. It's because the country's general culture and ideology works against both unions and social welfare.

You don't need unions to organize and demand things of the government. If people don't want to vote for social policies, unions won't make them want different things.
