The basic details of Hurricane Katrina hitting New Orleans in 2005 can be found on thousands of sites. What few other sites will mention is how George W Bush - with the help of Democratic Party leaders and the establishment media - helped drive many victims of Katrina out of work and relocate them out of New Orleans.
In an ideal world, New Orleans reconstruction work would have mostly been done by residents of New Orleans and other Americans. George Bush and the Democrats had other ideas. Taking various actions, Bush assisted connected contractors to employ illegal aliens, driving American hurrican victims out of work. That had huge financial and social costs, both immediate and indirect.
While those as different as Jesse Jackson and Phyllis Schlafly opposed what Bush was doing to some degree, those closer to the establishment assisted Bush. Those who helped Bush drive American hurricane victims out of work included Harry Reid, Linda Chavez, Raul Reyes of USA Today, Gregory Rodriguez of the Los Angeles Times, E. Eduardo Castillo of the Associated Press (also this and this), Ian Urbina of the New York Times, the National Council of La Raza, Peter Pae of the Los Angeles Times, Ruben Navarrette Jr., Jason Zengerle of the New Republic, and others.
If you want to do something about this, ask fiscal conservatives and libertarians (and Republicans who are still supporters of George Bush) questions #4 and #5.
