e companies and Visa, which all want to play a central role in tying together phones, retailers and banks into a new payment system. Google said Thursday that it's launching a trial of its payment system in San Francisco and New York in cooperation with MasterCard and Citibank. It is opening it up to consumers in the summer. It then plans to expand across the country. There has been talk of smart payment systems for years. Google faces the same hurdles that have stifled previous trials. The new Google Wallet will initially work on only one smartphone, the Google Nexus S 4G carried by Sprint Nextel Corp. It will connect only to MasterCard PayPass terminals. There are more than 135,000 of those in U.S. stores and restaurants, but that's only a small fraction of the total number. Google calls it a "single-tap" solution, meaning shoppers should be able to pay with a single tap of their phone on a payment terminal, or a swipe past it. But in a demonstration at Thursday's New York event, a Google executive had to tap twice, then sign on the screen of the terminal provided by retail partner American Eagle Outfitters Inc. to get a purchase through. Osama Bedier, Google's vice president of payments, said it was up to the retailer to decide if the Admiral Mullen told the West Point graduating class that, “I fear they do not know us….I fear they do not comprehend the full weight of the burden we carry or the price we pay when we return from battle.”  It makes it far to easy for our political leaders to commit armed forces to battle when their own children will never have to fight or die. Or to continue in a war they are unable to win, but unwilling to end because the broad mass of Americans don’t rise up and say no. Or commit overwhelming force to a war we need to win, because they worry voters would balk if they knew the real price tag in lives and treasure.  When only a tiny fraction of our people pay the price of our politicians’ mistakes, those politicians are rarely held accountable. More Members of Congress have been to law school than officer candidate school. In recent years our presidents have not been veterans, or if so, not combat veterans.  We’ve come to expect that our presidential candidates spend several years in law school or business school – but it’s a rarity if they’ve done a tour of duty in the military. Does that leave them lacking as leaders when one of the most important constitutional responsibilities of a president is to be commander in chief, or Congressmen to vote a declaration of war and appropriate funds for the common defense?  What do they know of the sacrifices and responsibilities of our servicemen and women, when the closest they’ve come is marching next to them in a Memorial Day parade?  We’re now engaged in at least two unpopular wars -- a third if you count Libya -- and none of them have gone well. Our nation is understandably war weary and concerned about the burden on our nation’s budget at a time of financial crisis. As a country, we seem more disconnected from each other – and from our leaders – as any time in our history. And the notion of “ask not what your country can do, but what you can do for your country” seems as alien and anachronistic as a victory garden in the backyard. Isn’t it time we think again about national service?  Not bringing back the draft, or mandatory military service -- the military doesn’t want that any more than the population. But what about some sort of national military or public service for America’s youth?  Every few years someone introduces legislation calling for national public service. In times of plenty, it was unrealistic. Why would any of our young people want to give up high paying jobs for a year or two, for low paying jobs of sacrifice? But times are different now. Those high paying jobs have dried up, and our young people often find no jobs at all. Youth unemployment is at an all time high, and unlikely to improve anytime soon.  Now is the time to seize the moment, and make lemonade out of lemons.  Let’s reconsider national public service, and ask that our 18-year-olds to spend 18 months serving their country – in the military, rebuilding our parks system, teaching in schools, helping out in senior citizen centers.  Today our high school and college graduates compete fiercely for internships – often unpaid – just for the chance to get some real life experience and get off mom and dad’s couch. Wouldn’t it be better for them to spend 18 months putting something back in, doing something to help the country, moving beyond their comfort zones, meeting their fellow countrymen from all walks of life? Understanding that America is not a collecti
