Capitalist economies with no welfare state (laissez faire) converge to an economy where people have to work to survive, which depresses wages, which can very easily (and reliably) bring about a vicious cycle. The end state of this is one where the lucky among the proletariat become servants (paid a pittance, but in a nice house and well-fed, enabling a very nice life in comparison to the alternative) while the unlucky and poorly-connected (who cannot even find employment as domestic servants) starve. This would be very damaging to minorities and Latinos, because the upper classes would demand (and be able to get, due to the collapsed economy) white, formerly middle-class, maids and nannies.
Minimum wage and welfare programs aren't good just for their direct beneficiaries, but for a lot of people, because they raise the bar across the board. If minimum wage is $8/hour, then skilled workers will expect $15 and entry-level white-collar will expect $20. Increase that to $10, and skilled workers are now asking for $18, and white collar is asking for $25. Although this causes "inflation", it's the good kind because it represents a wealth transfer away from legacy and in favor of labor.
On the other hand, if there is no minimum wage (which is similar to a basic income but contingent on working) then the reference point collapses and everyone gets poorer.
