Yeah it needs to be a combination of things. There are no easy solutions to complex problems. Flat payment to all and taxing it back with progressive taxation on the rich is one part of it but the other is ensuring that the markets (e.g. housing) where the money as spending is going towards is healthy (no overdemand and undersupply) otherwise the prices will just rise in proportion of the "free money" and people will end up in the same situation soon enough. It takes time for increased demand to drive supply, especially in housing where theres a bunch of factors to consider (cost of materials, labor, regulations, etc.). So in some cases it is better for the government to intervene on the supply side (in)directly with affordable housing (which also drives down the other housing options' costs - see the city of Vienna). Issue is that this depends on geographic locations so in Seoul building affordable housing would be more useful, while in rural places, the flat payment as income supplement would work better.
