Differences between returns on capital and economic growth alone will not result in any increase in inequality. If everyone achieves the same rate of return, inequality can only remain flat - bignum x exp(rt) / smallnum x exp(rt) = bignum / smallnum = const. If some people have income and save it inequality will go down: bignum x exp(rt) / smallnum x exp(rt) < (bignum x exp(rt) + k) / (smallnum x exp(rt) + k). All r > g directly implies is that the ratio of capital stock to income will increase. I.e., we'll move from a situation with one factory (worth $1M) producing $1000/month in income to a situation with two factories (worth $2M) producing $1500/month in income. In this case, r=100% but g = 50%.
