What makes anyone think the minimum wage is supposed to be enough for the sole support of someone?
Marketing does.
The same kind of marketing the packages billions in corporate welfare to Con Agra, ADM, et al as 'helping america's farmers.' The same kind of marketing that sends you 'statements' about how much Social Security 'benefits' are in your 'account' and perpetuates the myth that you are paying for your own retirement, rather than paying for current retirees.
Or packages lavish teacher retirement packages and bloated education bureaucracy as being "for the kids." Or props up massive university budgets on the basis of 'helping students.'
Or turns massive government land grabs that destroy the environment into "conservation" measures.
I'd go on, but that would be unsporting.
