Marx vs. Weber: Goals of Capitalism

To me, I think this is how I identify Marx and Weber. Marx is more focus on the reality of capitalism while Weber is focusing on the religion and culture of capitalism. Both of them actually could apply to every era of history, but for the 21st century, I think we are more in the Marx's concept. The capitalism which Marx you emphasised was the accumulation of wealth- maximise profit and minimise cost. According to Piketty's concept of Capital in the Twenty-First Century, the accumulation of wealth from the rich generally grow faster than the output and wage. No matter which religion or culture you are in, people in today were more focusing on saving and earning money because of inflation and standard of living. Without the accumulation of wealth, the middle and lower class cannot survive in society. Although Weber's concept of Calvinism or Lutherism might give the working class or lower class a comfort in their work force, the upper and working class still have the goal to earn as much as they could from the labor market. Can anyone apply Weber's concept or Marx's concept to another era or century from the history?
