Yeah, but there's a difference between a "mixed economy" and "full on free stuff"
i usually don't respond to matthew seriously but im gonna make an example out of him
"free stuff" is a stupid buzzword used by people who think socialism is giving people anything they want while the poor rich people suffer in poverty. in reality, the government would be supplying people with the basic necessities to survive until they can get a job, a job that would support them well enough to eliminate the need for government welfare.
welfare has a bad stigma because of all the people who stay on welfare instead of taking a job, but honestly it's way smarter to stay on welfare than it is to get a job if you're genuinely in poverty. because wages are not guaranteed to be adequate enough to support an individual, let alone a family, and welfare usually is at least slightly better, people stay on welfare. this essentially punishes anybody who actually pursues a job in an attempt to leave poverty, so obviously a lot of people in that situation currently would, rightfully so, choose welfare. this is also the problem with socializing some aspects of the economy and leaving the tangential parts up to the will of businesses.
if jobs, no matter what they are, are able to support you better than welfare while still being enough to actually support you, more people are gonna want jobs.
