3. It would limit the influence of unions, civilian oversight committees, and similar institutions.
Democratic Socialism would cede the rights of workers to the government through employment. If the government decides that having a union is not in their best interest, then they can get rid of it. Public employees have already experienced this in government structures that are closer to capitalism. That means there is a greater potential for unsafe work places, lower wages, and less overall incentive to work if all the physical needs of an individual are automatically met by the government.
4. It can reduce innovation.
There may be an advantage in Democratic Socialism in that people with specific skills or talents are placed into jobs that directly benefit from that experience. At the same time, however, production within a socialism-style government structures tends to focus on domestic needs instead of new opportunities. That limits innovation because there is little, if any, competition with the government to develop new ideas. Over time, that means the society can lag behind others that incentivize innovation.
5. It can create more bureaucracy.
The government will want to determine who is eligible to receive specific benefits. Applicants must fill out paperwork to prove their eligibility. Ongoing renewals must be processed. The goal of Democratic Socialism may be to streamline society and equalize access to services, but more bureaucracy is created in doing so. That means it could take much more time to make services available to those who need them.
6. It creates more government spending.
For an economy to grow, there must be a balance between domestic and foreign trade. As innovation declines and manufacturing grows stagnant, fewer international opportunities develop. That means the government may be forced to import more items, creating trade deficits with their neighbors. Without innovation, maintenance and repairs overages become common as equipment ages. In time, the government spends more than it would if it had simply invested capital into existing systems to upgrade them.
7. It can create a lack of societal motivation.
There will always be people within any society that do not participate in the workforce. In the United States right now, about one-third of all people who are of a working age are choosing not to join the workforce. Under a system of Democratic Socialism, those figures could increase even further. If there is no reward for producing more than someone else, yet both individuals have their basic needs met, the individual working is more likely to give up than the individual not working choosing to join the workforce.
