Capitalism is an economic system that has as it's goal the concentration of every product and service under the umbrella of a single company or corporation.
Capitalism says that if a particular company is more efficient than it's competitors it will capture the market. And if the company captures the market then it can charge any price for its product(s) or services which will produce the maximum profit.
What this means for the consumer is that as the market shrinks and competition is eliminated the cost of goods and services increases. And if there is a single source of purchase for a needed product or service those with lower incomes may not be able to afford the product or service. Insulin is an example today.
Another goal of capitalism, that complements the first goal, is profit. The capitalist seeks to maximize as much profit as is possible.
With the duel objectives of monopoly and profit as the only goals there is no consideration of the social impact nor for empathy for individuals by the company or the managers or stockholders.

So should capitalism be unrestrained in the market the effect on the futures of individuals and families would depend on their ability to pay for needed goods and services at the price set by the wining companies or company. Again insulin is an example of market control and the effect on profit at the expense of the individual or / and groups of individuals. If the individual cannot afford the insulin the company takes no responsibility in the individual's death for lack of their product.

I just retired from an ESOP company. That is definitely the right way to go. I like ownership to stay in the hands of the people not the government. We need to take the good points of capitalism and mix with good parts of socialism. That is what the Democratic Socialists want. Very different than straight Marxist Socialism/Communism
