With Walmart(WMT) - Get Report sales and profits falling, pundits are asking if the U.S. economy is again headed down. Hardly.

Like IBM(IBM) - Get Report and other business icons in trouble, the Arkansas retailer is simply being squeezed by better competitors -- mainly Americans -- heralding a new age of American innovation. This is the new American century. 

Look at Walmart -- its recipe for success was simple. Through a detailed knowledge of supplier costs, disciplined supply chain management and low wages for store personnel the retail bargained hard with manufacturers and delivered goods at the lowest prices.

Unfortunately, its methods were hardly occult and others, including Dollar General(DG) - Get Report and Target(TGT) - Get Report caught on, undermining the Arkansas behemoth's competitive edge. In addition, other big employers such as McDonald's(MCD) - Get Report has put Walmart under increasing political pressure to pay its workers more.

Walmart attributes 75% of its drop in projected earnings to raising entry-level wages to $9 an hour, but employers don't get much paying a single mom so little. Shoppers complain its stores are unfriendly, messy and often poorly stocked. Other bargain retailers are suffering a similar malaise because millennials and older folks willing to change buying habits can get better products, cheaper online.

Meanwhile, for $99 a year, Amazon's(AMZN) - Get Report Prime provides prime-time TV and free shipping directly from the folks that make products. That virtual marketplace offers more choice, competition that drives down prices and cuts out altogether the retail supply chain, the shipping to warehouses and stores and retailers inventory carrying costs. That drives consumer prices to their lowest possible level.

Brick-and-mortar retail is not going away. But when consumers know exactly what they want they can save even more money by avoiding Walmart's congested parking lots and "courteous" employees.

Many similar, seismic changes are occurring at IBM.

The tech giant's competitive advantage was in helping moderate-sized and large companies manage on-site computing, software and related services-and then using the resulting access to hawk its mainframes, software and businesses services, such as Lotus Notes email and artificial intelligence systems.

Unfortunately for IBM and rivals Hewlett-Packard(HPQ) - Get Report , Dell and Oracle(ORCL) - Get Report , businesses large and small can rent or lease computer services more cheaply on "the cloud." Amazon Web Services leads by offering 10 times the cloud computing capacity as the next 14 largest rivals combined, and boasts clients including General Electric(GE) - Get Report , BMW and Capital One(COF) - Get Report .

Amazon is building a marketplace for software and services from a wide range of suppliers, with obvious advantages over an IBM consultant who has an interest in hawking Big Blue's offerings. Many other firms including Juniper Networks(JNPR) - Get Report , Equinix(EQIX) - Get Report and Red Hat(RHT) - Get Report are also offer computing power, software and other services on the web.

Both Walmart and IBM are moving what they do to the Web and cloud but both have CEOs who are more comfortable with another age and executives who feel receive compensation their revenue and earnings trends indicate they hardly deserve.

The good news is that so many of the leaders in e-commerce and the infrastructures of data management, computing, software and business services that define the cloud, are American.

The story repeats in so many places. Tesla(TSLA) - Get Report -- not BMW or Toyota(TM) - Get Report -- offers electric cars that break performance meters. Twitter(TWTR) - Get Report  and Facebook(FB) - Get Report  turn all of humanity into a village square.

We entered the 21st century being told by so many economists and pundits this would be the "Asian Century." China's woes and inept leadership throw cold water on that thinking.

Just as in Henry Ford's age, the future belongs to people with a "better idea." Thankfully, many of those are the American entrepreneurs who are defining this new American century.
