Capitalism doesn't imply the limitations you suggest:

"Capitalism : a way of organizing an economy so that the things that are used to make and transport products (such as land, oil, factories, ships, etc.) are owned by individual people and companies rather than by the government"
or
" Capitalism : an economic system characterized by private or corporate ownership of capital goods, by investments that are determined by private decision, and by prices, production, and the distribution of goods that are determined mainly by competition in a free market"
