I see CONZ have no viable answers to the OP.
Usual.
First, I am not a conservative.
Now the op claimed that corporations will benefit from UHC. I am assuimg this is due to the corporations not paying for it.
So tell us, who is paying for it? Healthcare just does not fall from the sky like Manna, OK
Also, let us assume it is paid by the workers. What is the difference in a worker buying insurance for him/herself versus the worker paying for UHC through their wages?
Not much if we do not consider choice of policy, support from the employer(which exist in the current system) and freedom from a second layer of bureaucracy that will come in due to the presence of the government. (The first layer was due to the private entity selling the policy. That is already a mess. Adding government bureaucrats is not an improvement.)
So even if it "helps" the American coroporation, it is not a "help" to the overall economy due to the end-consumer/worker is getting hit with an inconvience that does not make the entire economy more efficient. In fact, there is more restriction on the employee due to the reasons listed.
