By "instability" do you mean draconian legislation like SOPA / PIPA / CISPA / NDAA / TPP / TTIP and all the other nasty shit we're supposed to keep "pushing back" on, because otherwise they'll just inflict it all on us, and then it's too bad because we kind-of-sort-of asked for it by voting in the bums and not resisting.. ? :P
Let's hope we never experience whatever catastrophic failure would follow from pushing back too successfully!
We don't need to; we already know how it looks like. It went to the opposite extreme when the Industrial Revolution started; our great grandfathers and their great grandfathers paid in blood to restore the balance, so that we may enjoy relatively humane employment conditions the current generation of entrepreneurs wants to fight against so hard.
So you think we're now experiencing too little draconian legislation then?
That's a ridiculous idea in the reality we live in.
> IMO we need to trim regulations here and there
Who's "we"?
Also, there is another reason to keep a diversity of ideologies: they serve as a check on each other. For example, allowing either capital or labor to gain too much power tends to cause problems. It is the competition between them that keeps power from consolidating on one ideology.
