Some things are worth preserving, some are not.

Walmart has increased the standard of living of the lower class quit considerably.

In the 1980's everything was kind of expensive. From 1990-2010 with the rise of real globalisation it was just unbelievable what could be had for a a few dollars.

I think most people would notice it if Walmart were to suddenly disappear.

That said, anything cultural is probably worth preserving, usually we don't price in those things well enough.

Also, 'quality' and other intangibles don't fare well into the equation.

So it's a matter of being really smart with the regulation, and hopefully sorting out the tax regimes as well so as to not allow the 'Ireland Tax Haven' scenarios.
