Something that rarely comes up in an Income Inequality discussion is the divide between government workers and private sector. (I will include large corporations in with govt, for obvious reasons).
Most feel they are underpaid and over worked. Ha-ha, right! Every govt retiree is essentially a multimillionaire. Consider that for every $1000 they get in retirement per month is like $1M in the bank at 1% (guaranteed & no risk) for life. and life of spouse. No stock market worries for them.
Compare to the retirement of the self employed plumber, electrician, truck driver, lettuce picker who actually provides indispensable services
