Not all capitalism is equal though. The overlap between socialism and capitalism is state capitalism, and it turns out if you want affordable childcare, healthcare, utilities, public transport, etc. then state capitalism is the way to go.
Taxes can be levied on productive businesses that are in ruthless competition in the free and international market. No productive businesses = nothing to redistribute. No international business == no imports. Everybody is poor and hungry.
The free market economy is ruthlessly efficient in the national and international market due to involution and strategic loans from state-owned banks.
