Final answer:
President Trump proposed several items to Congress, notably tax reform with reduced taxes for businesses to stimulate investment, a surge in military spending, and attempts at healthcare reform. However, he did not propose a major increase in government healthcare spending or pass significant infrastructure legislation.
Step-by-step explanation:
During his presidency, Donald Trump proposed several key items as part of his domestic agenda that he sent to Congress. Among these proposals were tax reform, which included a reduction in taxes for businesses that increase investment, a significant legislative effort that ultimately led to the enactment of the Tax Cuts and Jobs Act of 2017. Another area of focus was military spending, where President Trump advocated for a surge in military spending, aiming to strengthen the U.S. Armed Forces. Furthermore, the Trump administration made attempts at healthcare reform, including efforts to repeal and replace the Affordable Care Act, although these attempts did not fully come to fruition.
In terms of increasing government expenditure, the Trump administration did not seek a major increase in what the U.S. government spends on healthcare, unlike previous proposals from other administrations that might, for example, have included increased federal spending on Medicare or education. Therefore, if we relate this to Truman's era, President Trump's agenda did not encompass certain initiatives such as national healthcare, which Truman's domestic agenda included but was rejected by Congress. Likewise, during Trump's presidency, there were discussions about an infrastructure bill, which looked at areas such as spending on airports and air traffic control, but this did not culminate in a significant legislation comparable to the areas of tax reform or military spending.
