The problem with these sort of blanket policies is that they often have unexpected consequences- For instance, if we hand out lots of checks to the underemployed it MIGHT make their lives better or it MIGHT cause macroeconomic disruptions tied to the labor market that triggers inflation on basic staples, making the underemployed worse off than they were before the new policies. I'm sympathetic do the idea of saying "we've go to do something" but history unfortunately shows instances where "doing something" is often worse than "doing nothing" so you have to be very very careful.
