The above chart reveals how a tipping point was reached for new investment once social welfare spending rose above 10% of personalincome and began claiming a larger share of income than new investment.
Once social welfare spending exceeded 10% of personalincome, however consuming a greater share of income than new investment average annual net private investment began to fall steadily, eventually by 29% to an average 7.3% of personalincome.
In its place we can then simplify personal taxation: just treat all investmentincome (yes, dividends and capital gains) the same as we treat any other form of income, to be taxed at whatever is the appropriate marginal rate for the total income of the recipient.
