Well, there are three primary actors in the economic marketplace. The consumers, the vendors, and the government.
The government is supposed to act only to maintain a level playing field between vendors/vendors, vendors/consumers, and consumers/consumers.
Now, that’s very vague, and both parties can argue they are doing just that; the Democrats will claim that it’s their regulations that create the level playing field, the GOP will claim that outside of infrastructure and some basic consumer protection, regulations unbalance the playing field rather than balance it.
I can argue both sides of that coin convincingly. :-).
Unfortunately, it’s difficult to balance between (large) vendor and (small) vendor, and vendor and consumer, when the vendor is paying off the politicians. This has created a situation in the US where the vendors tend to have the upper hand legally and in commerce.
Fixing that is like being served a plate of spaghetti, and having to take each individual strand out one and a time and lay it out on another plate before you eat.
This is why Hayek and Friedman wanted the government to just stay out of it, period. They realized that the conflicts of interest between the parties cannot be solved by government, especially when the government itself is compromised. The Invisible Hand may (and will) smack the little guy to the ground now and again, but trying to PREVENT that from happening destines the little guy to spend his entire life under two thumbs, that of the Hand, and of the government who keeps trying to “help.”
