This week marks the final edition of the Weekly Pulse. I have been writing the newsletter since 2008 and it has certainly been an exciting time to be covering health care in the United States. Thanks to all the Media Consortium journalists whose work I've featured over the years, and thanks to our loyal readers, tipsters, Tweeters, and Facebook fans.

As the Pulse winds down, we look ahead to some of the most pressing health-care issues facing the nation: The Republican war on Medicare and Medicaid and the anti-choice onslaught.

89 arrested over Ryan plan

Too often, the immigration debate in this country ignores the role U.S. foreign policy plays in fueling unauthorized immigration. But as the Obama administration continues to stall on immigration reform in the United States—all the while moving forward with two contentious trade agreements with Colombia and Panama—the connections between the two are worth examining.

Robert Parry in In These Times examines how Paul Ryan's budget test would turn health care for the elderly into one big free-market death panel.

Ryan's plan privatizes Medicare, replacing it with premium support for insurance companies. That means the government would kick in a fixed amount of money towards insurance premiums for Americans over age 65. Ryan also wants to repeal the Affordable Care Act, which requires insurers to cover people with preexisting conditions. Ryan's plan doesn't guarantee that Americans over 65 could get insurance in the first place. Even if they could find an insurer willing to take them, there is no reason to believe that premium support would cover more than part of the cost.

Last week marked the centennial of the infamous Triangle Shirtwaist Factory Fire, in which 146 mostly immigrant workers died. The tragedy prompted widespread labour reforms in the United States, but its commemoration underscores the plight of immigrant workers similarly exploited today.

As Richard Greenwald notes at Working in These Times, the disaster marked "the moment that a strong collective working class demanded its citizenship rights," while today, "we are living in a time where organized labor is weak, fractured and leaderless." He concludes that a rebirth of labour must come, as it did in 1911, from today's new immigrant communities, which continue to bear the brunt of exploitative labour practices.

Arizona's business leaders, frustrated by the deep financial fallout of increasingly radical immigration proposals, successfully swayed state lawmakers into defeating five extremist anti-immigrant bills.

New America Media's Valeria Fernández reports that 60 executives from the likes of WellsFargo bank and U.S. Airways penned an open letter to state Senate President Russell Pearce last week, urging him to leave immigration policy to federal government. Julianne Hing at Colorlines.com has posted the letter in full, but here's the gist:

Vermont is poised to abolish most forms of private health insurance, Lauren Else reports for In These Times. The state's newly inaugurated Democratic governor, Peter Shumlin, unveiled his health insurance plan in early February. If the state legislature passes the bill, Vermont will become the first state to ban most forms of private health insurance.

The bill is getting support from some unlikely quarters:

Michigan's new Emergency Manager Law is already forcing major concessions from unions. The law gives the governor the power to declare a city insolvent and appoint an emergency manager with virtually unlimited power to reorganize every aspect of city business, including dissolving the city entirely. The emergency manager even has the power to terminate collective bargaining agreements.

Arizona lawmakers are considering two bills that would block undocumented immigrants' access to education to an even greater degree than current state law.

SB 1611 -- sponsored by state Senate President Russell Pearce (R) -- bans undocumented students from enrolling in kindergarten through 12th grade and attending community college. It also requires schools to notify law enforcement agencies if parents are unable to submit proof that their child is a citizen or legal resident. The other bill, SB 1407, requires schools to submit data on the number of enrolled undocumented and authorized immigrants alike, under threat of funding loss.

Stricter immigration enforcement and reduced economic opportunities in Arizona has pushed many undocumented immigrants out of the state to look for work.

While restrictionist lawmakers, whose stated objective over the last year has been to drive attrition through enforcement, are satisfied, it's not exactly the outcome they've been waiting for. Rather than return to their home countries, most immigrants are instead relocating to surrounding states -- a trend that's prompting legislators in other states to approach immigration reform in radically different ways.

With millions of Americans out of work, House Republicans are focusing in on real priorities: decimating private abortion coverage and crippling public funding for abortion, as Jessica Arons reports in RH Reality Check.
