And during the Bush Administration, it was the Left rallying against Big Brother Government which the neocons didn't seem to have a problem with. Each side sees the government as a corrupt tool manipulated by their rival. Fight fire with fire, as usual. It's all justified by the belief that Sacrifice is necessary for Security, but both sides define Security differently. The Left favors entitlements and safety nets for the underclass. The Right prefers National Defense.
Your focus (blame Obama, blame liberals, blame unions) isn't going to bring the country together. If the fractures continue and faith in the system collapses, then it's natural for the underclass to do their own brand of outsourcing through criminal economies. At that point, we're all screwed and conservatives may then welcome Big Government in the form of a Police state (for the good of our security, of course

).
I prefer we move away from the usual blame game and work towards alternative solutions. For example, in the case of over-budget entitlement costs, we could transfer this to a localized, virtual credit network. Entities like community unions could work with local companies (creating jobs) to then manage it through a variety of innovative recruitment, distribution, marketing and service methods (thus enabling benefits while limiting expenses). Get the entitlement receivers, government, unions, businesses all working together to find compromised solutions that serve everyone's interests. This should be workable when executed effectively and with technology to minimize costs. But it requires a healthy degree of trust and cooperation which are in short supply these days.
