This would be a great idea but it could be easily corrupted.
Absolutely... The problem I see is even with all the money in the world it will still have to go through the government bureaucracy to be implemented where it needs to go.
“...but it could be easily corrupted.”
...going a bit fast for me here but it sounds like corruption from the git-go. I thought one way or ‘tuther, Mexico was going to pay for “The Wall”. Whether Mexican Treasury or US Treasury, funding is there. And sharing the burden of funding across programs, the sum of other programs will not skip a beat. Two things are missing; Mexico has no incentive to pay and our politicians lack WILL.
Lipstick on a pig or a rose by another name, sounds like a voluntary tax. If only it would remain a “once in a lifetime opportunity”.
Voluntary Tax; other than being the premise of how IRS operates, if approved, this scheme will end up like Spanish-American War surtax on telephone service that survived nearly a century.
