>> You don't see big investments in new technology, science, infrastructure, or other complex and difficult areas because by and large the financiers do not understand these things. Isn't this the role of of venture capitalists to understand those things(with regards to science and tech), and they build specific expertise to understand those things(including hiring top notch entrepreneurs )? But venture returns are not that great(average 7% annual) which explains the little money invested in them(less than $15 billion in 2013).
