All those things you listed involve difficult trade-offs. Increased capital taxes would on the margin decrease capital expenditures, and thereby hurt income growth in long-term due to lack of productivity gains. That's the last thing we'd want if our goal was to increase income. IMHO both income and capital gains taxes should be cut substantially. Cheaper property necessitates more property, and at least here in US not building in the suburbs has become presidential campaign fodder. The most economically productive cities like SF have some of the most complex zoning and planning regulations that make boosting supply challenging. If I had to guess what the right answer would be, it'd be higher minimum wages + stronger unemployment benefits that are designed to get folks back to work. Germany's post-Hartz system is an example of the latter. Higher minimum wages would force people out of work, but they would also motivate higher cap-ex in automation. Higher labor costs would make certain overly expensive automation projects more tractable to corporate management. The unemployed would get an opportunity to retrain for better, higher paying jobs and do so while having basic needs met. You can probably see though how this solution is basically impossible in the current political climate.
