With the Federal minimum wage currently at $7.25/hr, that’s just $15k/year at full-time. That puts many minimum wage workers below many countries’ average wages [1]. But that’s before adjusting for purchasing power parity.
Being a single earner on minimum wage effectively guarantees you and your family will be in poverty in the US. That is effectively not true in most countries in Europe, even the poor ones. You don’t get to live well or anything, but you certainly aren’t planning on poverty.
[1] California, and San Francisco in particular, have a higher minimum wage but also higher expenses. Worse, many low-education workers are waitresses, which often have a “tipped minimum wage” as low as $2.15/hr before tips (again, San Francisco doesn’t do this, but it’s expensive to live here).
Minimum wage is insufficient yet to put all population into poverty.
If we increase minimum wage to, say, $100/hour, then 99% of population would be not able to find any jobs [that pay minimum wage or more] and that would, effectively, put 99% of population into poverty.
With current $7.25/hr minimum wage only few percent of population cannot find jobs because they do not have enough skills to get minimum wage job.
