"World Class" is a very subjective term and, it's open to varying definitions. For example, McDonald's is a World Class restaurant. Is it the best quality? Is it something that you want to live on? If you define "Top-Tier" as having consistent quality and availability in every world market, then McD's is a Top-Tier restaurant.
Also, "Made-In-America" is subject to definition. For example, the federal government has requirements for items that must be made in America that include percentages of materials and allowances for foreign components and raw materials that are assembled in America. Some definitions even allow for NAFTA goods to be labeled "Made in America."
As a recovering attorney, I don't want to be accused of asking what the definition of "is" is but, it's important to have a basis for understanding the labels that are thrown around in discussions.
My $.02 is product evaluations should be made based upon actual performance. This can include the products and/or manufacturer's stability and impact on the market in addition to its quality and consistency.
