How did laissez faire government policies encourage growth?

The economic system of laissez-faire has several elements:

1) respect for private property

2) freedom to start and own a business

3) free markets in trade (that is, no government price controls or excessive intervention)

These government policies encouraged growth because the government took a step back from the businesses and people can now live so much easier, without worrying about the government collecting the food or stuff they make.

It allowed businesses to operate with less regulation
