Governments in civilized countries have imposed a statutory minimum salary to avoid exploitative employers from paying starvation wages but I suppose that offends your libertarian principles!
The problem with even the most generous statutory minimum wage is that it is seldom increased to keep up with inflation. The country where live, Luxembourg, is one of the few exceptions, that still indexes the statutory minimum wage (and all pensions, benefits and salaries both public and private) to the rate of inflation. When a 2.5% increase in prices is reached, everyone gets a 2.5% increase in salaries etc.
Welfare is not and never has been what folk want; what they want is decent work with pay that enables them to pay their rent or their mortgage and raise their families if they have one. It's the billionaires who run the world's largest corporations who are amongst the worst offenders for paying starvation wages with Bezos being a fine example!
