Learning about capitalism

Capitalism is a market-driven economy. The state does not intervene in the economy, leaving it up to market forces to shape society and life. 
How come we bailed out the banks?
Can you remember how many companies have been bailed out? 
They don't pay tax and then when they fail we
 bail them out.

Wakey wakey

I woke up this morning and wondered who profited the most when the big businesses don't pay their tax.
I know the  board members probably get bigger bonuses what about the share holders?
I thought I understood how capitalism worked but it is more complicated than I realised. So I googled a definition.
Capitalism is an economic system. In it

1. the government plays a secondary role. 

Does this mean that  governments are ruled by BIG Business?

2.People and companies make most of the decisions, and own most of the property. ... 

Who are the people?

3.The means of production are largely or entirely privately owned (by individuals or companies) and operated for profit.

Owning the means of production is key to controlling the working class. Who actually  produces?
The workers who do the WORK it seems come bottom of the heap.
 And when the company do not pay tax the share holders must rub their hands.
