You seem to be fairly heavily invested in this. What legislation will benefit us (Canadian)?
Any number of actions might benefit both countries.
Topping my list would be increased employment standards.
This would help reduce inequality and poverty in the United States and increase the standard of living, even for many middle income Americans.
At the same time, that increase in standards would reduce the gap between current U.S. and Canadian standards, giving us room to raise our standards while remaining at least as competitive as today.
To offer but 3 examples.
Currently the U.S. has no Federal or State mandate for Paid Vacation. Not a single day. Canada is predominantly at 2 weeks, with 3 weeks after 3-15 years of service. (though 3 weeks is the baseline for Sask.)
Most of the developed world is at 4 weeks. A perpetual argument here against increasing the standard is the non-existent American number.
A simple federal mandate of 2 weeks (more would be better) would offer leeway for every province to go to 3 weeks initially and 4 weeks after 5 years, while improving on our competitive position.
It would also be an immediate 4% pay raise for the least well off (employed) Americans.
A second, similar example would be the absence of any paid maternity or parental leave at the Federal level in the U.S. Several states (about 10) have such mandates varying from six weeks to six months.
Simply having a core mandate of just 17 weeks (matching Canada's maternity leave) would not only be an enormous boost to new mothers in the U.S. including many middle income ones who get little or no leave, even if unpaid.
It would also increase the cost of U.S. labour giving Canada room to enrich our program in terms of income reimbursement from 55% to 75% while actually maintaining relative competitiveness.
Finally, I would look to Minimum Wage. The U.S. Federal Minimum Wage, which is the default State Minimum Wage in many southern States, is a mere $7.25USD per hour
While $15USD over the next few years would be great; even an immediate rise to $10USD and a phased raise to $14 over 4 years would drastically reduce U.S. poverty and would also provide competitive space for minimum wage increases here.
$14USD is equal to $18.24CAD
An amendment to the Constitution under Article 5 can be proposed by 2/3 of both the House and Senate OR 2/3 of the state legislatures. However, it must be ratified by 3/4 of the states. I doubt the Congress (House + Senate) would initiate a process to diminish itself. Also, what would you replace it with? Under A.5, no amendment can diminish state representation. Of course the Article could itself be amended but I wouldn't hold my breath.
I'm not holding my breath either.
I see no reason to feel sympathy pains.
That said, I think its the right course of action, even if its one that may need to wait several years.
