I am honestly hesitant about supporting a person who doesnt seem to understand basic basic economics.
As for the minimum wage, I think a 15 dollar minimum wage would be great for the urban and suburban areas, but would be quite bad for rural areas. I think a much much better option would be to raise the minimum wage to a price that almost all areas can support, and then just increase transfer payments to poor people. That way, you will help poor people more and reduce/eliminate the negative effects of increasing the minimum wage in areas that can't really support, or at least won't see any benefits from increasing the minimum wage substantially.
Nah. So you're a country with major natural resources (say Canada) and a solid manufacturing sector. Opening up free trade nukes the manufacturing sector (can't compete without protection) and spikes the resources. Hundreds of thousands middle class jobs lost, hundreds of thousands of corporate middle class white collar jobs lost, a few hundred thousand blue collar jobs added, a few tens of thousand upper-class finance jobs added. Major increase in income differences favoured rich, less jobs overall, some other nation makes some more money. Economy and per capita GDP still increase, but in bad ways.
Or, say, --insert major African nation with huge natural resources-- vs Japan. One country mounted massive protectionism to build industry and use that to fund schools and expand into high tech while fending off Western corporations. The other enjoyed free trade, remained super-poor, was exploited by Western government backed corporations, and still blows today (yes, long story, but even setting aside the civil war regions doesn't help...). Germany, Japan, key countries use strategic protectionism in favour of huge government-forced taxes On rich/upper class to poor/middle class people (though yes, they keep more of that then modern America though less then 1950s America).
Yes, global free trade does increase global living standards, although distributed terribly (finance, corporation management, and abused poor labour). America in particular, however, would do much better with protectionism. And unions, but ya know...
Just look at real adjusted income for the middle class. Hasn't moved up in 4ish decades.
As for the minimum wage you want a negative income tax/guaranteed annual income. Which, along with better-than-current-plan healthcare, was scuttled in the early '70s because the Democratic Party thought their 1976 President would get better versions. (That said, Nixon also didn't care about domestic affairs so he never pushed hard enough on either. Plus he hated Kennedys, and Ted was key on healthcare... though yeah, Ted was huge on killing healthcare, alas.)
NIT/GAI (or, see, earned income tax credit for the mini-version) are rather unlikely given multi-decade Republican Party madness, so upping the minimum wage is the shitty alternative to better solutions.
Fun fact, Ronald Reagan wanted to be a nominee for a House seat in 1952, but the Democratic Party of LA rejected him for being too liberal.
