The parallel ~も~し、~も~ structure is the canonical way to list contrasting or parallel facts in Japanese — 'there's this one, AND there's that one.' 暮らし向き literally 'the direction/orientation of one's living' is a set term for 'standard of living, economic circumstances.' し is the clause-listing particle that connects facts without full subordination.
