That's quite universal, I think. The aspirational and the nouveaus tend to overdo it. They're out of their element, so they either indulge their existing habits and aspirations, behave unnaturally, or overcompensate according to what they think it means to be "upper class". It takes three generations or so for the habits, attitudes, concerns, and sensibilities to sink in. By then, their children and grandchildren are likely to have squandered their wealth.
