Insofar as social mobility may be stifled now, many contend it's in large part to government administration causing a sharp increase in taxpayer liability (you may not be billed for it yet, but your share of the debt is enormous and growing fast) and economic uncertainty (sporadic currency pumping, encouragement of class envy, and rule thrashing on healthcare etc). Hard for employers to hire & give raises (the core of social mobility) when economic future is so unpredictable and depressing.
