Why has American prosperity not spilled over into Mexico?

How has the raising North American tide of Canada and the USA not brought Mexico up with it?

If you’ve gone to the trouble of reading my details, I’ll give you three schools of my thought:

1.) Mexico is so buffeted on the other border by contrary forces that no stabilization is possible.

2.) Mexico is so weak and ungovernable that the US cannot support a viable government there, long term.

3.) Mexico being weak it in the long-term interests of the US. In that, if we build Mexico up as a superpower and they turn against us, we are screwed.
