It's not 1 single charity.
It's ALL OF THEM. Every single food pantry, every single church, every single soup kitchen, every single clothing donation, every single charitable person...frankly, Welfare, foodstamps, WIC and the like can't hold a candle to that when it comes to truly meaningful aid to those who need it. And I'm talking aid that helps lift people up so they can find their way on their own. What the government does has no impact there. The government creates and fosters reliance on the government. True charity does not.
Those all indeed help, but we are talking economies of scale with what the Welfare system does, and two doors contolled by Panama and Egypt which the US gov can deal with better than private entities.
Though I agree private charities help a great deal; Goodwill is great for getting decent stuff without a retail mark-up, and soup kitchens are vital. I think a work requirement, or at least a work bonus, is a reasonable conversation to have about Welfare and such. But I still think UBI would streamline a lot of the stuff we do through three or four different gov channels right now.
Now, I do not think Biden or co could do UBI or reform Welfare competently, and it would have been a stretch for even Trump to pull it off, if he were so inclined.
But it doesn't make the concept itself a bad thing, and the examples
@Bear Ribs provided show things like UBI can work alongside the Welfare system, and generally provide a net benefit to both the recipients of it, and the economies of their communities. Because it means some people start new businesses with that -psuedo-UBI money, not just not work.
What happens when the government can't meet it's own needs? Will welfare and all the other programs still be around?
Heck, look at all these heavily urbanized areas that have been controlled by Democrats for generations. They instituted HUGE levels of welfare and government intervention to 'help' the people. How has that actually worked out?
Some places Welfare has helped, some places it's harmed, some places it hasn't had much effect either way.
Also, not all blue cities are hellholes, or are fucked due to Welfare. That's cope a lot on the the Right use to pretend small towns can really compete when it comes to things like sports teams, music venues, food choice, ease of access to other places (before Wu Flu), and quality of medical services (not many small towns have Level 1 trauma care and the nearest Level 1 could be an hour plus away by car or even helo).
However, with UBI, we do have the Alaskan example to look at as a test case of how it might work in the US, so we have actual data points, and not just rhetoric, to work with. Again,
@Bear Ribs provided in his post many examples to look at.
Now, Alaska is fucked for a bunch of reasons currently, and a lot of them are outside the states ability to control in a meaningful way. Ships rarely cross the Gulf of Alaska in winter without good reason, there is no rail link to the Lower 48 at this point to ship goods enmasse overland, and oil is not high enough in price to offset the lost tourism and commerce that Wu Flu has caused.
As for what happens when the gov cannot meet it's own needs...are we talking a third world shithole needing outside charity just to keep it's people fed, like we see in some places now, or are you seriously implying private charity can replace major functions of a first world govs Welfare programs when shit hits the fan? Charity might help on a small scale, but it won't prevent another Great Depression, or alleviate supply chain bottlenecks.
