Classical liberals agreed with Thomas Hobbes that government had been created by individuals to protect themselves from each other and that the purpose of government should be to minimize conflict between individuals that would otherwise arise in a state of nature. These beliefs were complemented by a belief that labourers could be best motivated by financial incentive. This belief led to the passage of the Poor Law Amendment Act 1834, which limited the provision of social assistance, based on the idea that markets are the mechanism that most efficiently leads to wealth. Adopting Thomas Robert Malthus's population theory, they saw poor urban conditions as inevitable, believed population growth would outstrip food production and thus regarded that consequence desirable because starvation would help limit population growth. They opposed any income or wealth redistribution, believing it would be dissipated by the lowest orders.
