Answer:
In classic liberalism, the general idea is to liberate the market from regulations, thus enabling the corporations to conform a "process" which liberals think should run completely free and without restrictions, leaving it to the rules of nature and economics. This process, of course, in the end should bring wealth to everyone.
Neo-liberalism is the same formula, but applied to all the other systems liberals didn't think about, because they hadn't had a "welfare state" crisis yet, and with all the new variables modern technology introduced on the market during the two World Wars.
Neo-liberalism thinks the state and the government only interfere with the process, and that they should be reduced to the minimum only to disappear later, leaving the control of the public works to the corporations.
They also took the liberal ideas to the maximum, enabling entrepreneurs to not physically own anything, by virtualization of capital, artificial transactions, automatic trading, and complete usage of space and time.
