It is believed that even the simplest states in the simplest field theories are highly entangled. The main support for this statement comes from the Reeh-Schlieder theorem and calculations of entanglement entropy between a region of space and its complement. I will argue that these results do not provide much information about the entanglement between individual local degrees of freedom. I will then present a way of quantifying such entanglement and show that entanglement in field theory is significantly less ubiquitous than it is commonly believed.
