Democratic Germany produced a brand of glassware named Superfest. Through an innovative production process it was eight times harder than other types of glass making a Superfest glass very hard to break.
Planners in democratic Germany believed Superfest to have great potential as an export since it was superior to competing products. It turned out they were wrong, western distributors of glassware were not interested in selling their customers a glass that lasted and reduced the need to buy replacements. Following the annexation of democratic Germany the organisation tasked with dismantling Democratic Germany's industrial economy, the Treuhand, shut down the plant and abandoned the patent.
And that's why we can't have durable pint glasses under capitalism.
