"Capitalism is an economic system in which capital assets are privately owned and items are brought to market for profit. In a capitalist economy, the parties to a transaction determine the prices at which assets, goods, and services are exchanged,"
You cannot use an economic system to as a basis for national governance. If you did there would be very little place for war as it so unproductive and wasteful of resources. Strict adherence to Capitalism would decimate the arms industry.
One of the key components of a successful Capitalist system is labour, so the welfare of the population would be paramount as a healthy, flexible, educated supply of labour is vital to maximise productivity, therefore you would have lots of incentives and programs seeking to maximise employee health & happiness.
There would be much stricter controls over large multinationals that seek to gain economic advantage by reducing competition and gaining oligopolistic or monopolistic advantage, control prices, supplies, etc.
Proper Capitalism is a system to make effective use of available resources via a supply & demand model, unfortunately we don't punish severely enough the people seeking to distort and control these markets.
If we want real Capitalism we have to stop working with organisations and governments that constantly seek to control and/or destabilize Capitalist Markets like the Chinese, or the large banks or oil companies, if you want to see proper and efficient capitalism legislation is required.
