Two competing (or, possibly, complementary?) proposals for resolving income inequality and the hole that four decades of demand-side Reaganomics has dug us into are Universal Basic Income and a federal jobs guarantee (the former being a kind of "venture capital for everyone" that provides enough money to live without having to work for an employer; and the latter being a guarantee of a good, meaningful job of social value in sectors like infrastructure, education and caring professions).
Modern Monetary Theory is an economic paradigm that treats money as a utility that governments issue and tax in order to mobilize resources needed to provide the services that the public wants; it explains why some kinds of government spending leads to inflation while other kinds do not, and how sovereign states use different levers to control inflation, even when they're spending extraordinary sums, as in WWII.
Modern Monetary Theory (previously) is an economic philosophy based on the idea that all state spending is "deficit" spending, since money comes into existence when the government spends it, and when the government raises taxes, it does so in order to take that money out of existence, both in order to control inflation and to limit the concentration of power in the hands of the wealthy.
Modern Monetary Theory is the latest incarnation of chartalism, the economic theory that holds that government spending — and a federal jobs guarantee — doesn't create inflation, so long as the spending is on things that the private sector isn't buying: if a factory can produce ten widgets but is only producing five because that's all the public sector wants to buy, the government can put in an order for five more widgets, putting more workers to work, without driving up the price of widgets.
After 20 years of unprecedented lows, Canada's central bank is gradually raising rates; this, combined with strict rules on new loans, empty house taxes in overheated cities like Vancouver, and mandatory ownership disclosures (which keep money launderers out of the market) are depressing the Canadian housing market, and the prognosis is not good.
Alexandria Ocasio-Cortez (previously) stunned the Democratic establishment when she comprehensively kicked the ass of finance-friendly, seemingly untouchable Democrat-in-name-only incumbent Joe Crowley in a New York City primary race that she won on a Democratic Socialist platform of abolishing ICE, Medicare for all, a jobs guarantee, a housing guarantee, gun control, relief for Puerto Rico, and gun control.
Rep. Joe Crowley has been in Congress since 1999; he's the number four Dem in the House, representing a diverse district in the Bronx, and winning primaries in a solidly Democratic district by raising millions from his friends in the finance industry.
Bernie Sanders has a plan to solve America's wage stagnation and its long-neglected infrastructure: tax the super-rich and massively profitable corporations, then use the money to fix the multi-trillion-dollar infrastructure overhand left behind by decades of neglect, and hire Americans at $15/hour, plus full healthcare, to do the work.
