OTOH, the US having both a weak party system and a separation of power system makes it so that, to return to the upthread question about modern democracies, it does a lot more through executive orders than many modern democracies, which often have a strong-parties parliamentary system or a weaker Presidency, so that the executive has either less ability or less motivation to issue executive orders for matters that might be directly addresses by legislation.

Obama did a lot more through executive orders than his predecessors, in large part due to Congress obstructing all policy much more than its predecessors. IIRC, at a certain point he turned to executive orders to implement policy the best he could.

Also, most other modern democracies use parliamentary systems, in which the executive always has the majority in the legislature. In those cases, executive orders are less needed because the legislature and executive are much more likely to agree.
