Businesses exist to make a profit. Do you care that a washing machine or dishwasher replaces the work of what used to be a labor intensive activity? Do you care that construction workers are using backhoes instead of shovels (which would employ more people)?
Unionization made sense in part due to the very labor intensive work of the early 20th century. Conditions were poor and pay was low and you had massive numbers of people doing related work together. It made sense. Nowadays unionizing is like herding cats across disparate, ephemeral organizations.
I don't think you can take a 20th century approach to 21st century problems.
Workplaces aren't democracies.
