In his first months in power, Macron has defied street protests to loosen France's labour laws, moved to scrap the wealth tax and cut housing aid.
The 39-year-old, whose election win sidelined France's mainstream political parties and tore apart the country's traditional left-right divide, sought to reassure left-wing voters in his first live TV interview since taking office in May.
"We're taking care of the France where things aren't going well," Macron said. "I'm doing what I said I would do during the election campaign."
Macron angered unions last week with outspoken comments he made during a visit to a car parts factory, where scuffles erupted between police and workers protesting over job losses.
He said that reforms to overhaul France's unemployment insurance and professional training systems, which will be discussed in the next few weeks, would help the most in need while encouraging social mobility and merit.
Macron said the aim of scrapping the wealth tax was to help to retain talent in France and encourage the wealthy to invest.
"For our society to get better, we need people who succeed. We shouldn't be jealous of them, we should say: 'fantastic'," he said.
But the move has prompted opponents to label the former investment banker "president of the rich".
"He's not president of the rich, he is president of the super rich, those who funded his campaign," right-winger Nicolas Dupont-Aignan said.
Left-wing daily Liberation said on its Monday front page Macron was "brandishing individual success like a mantra" under the headline: "Succeed, bloody hell!", in a reference to his comments at the car parts factory.
In the more than hour-long interview at the Elysee palace that focused on his domestic agenda, Macron also said his economic reforms would start bearing fruit within two years.
"Unemployment is currently falling. You'll see the full effect of the reforms currently carried out by the government in 1-1/2 to two years," he said.
During the campaign, Macron promised to lower France's stubbornly high unemployment rate to 7 percent by the end of his mandate from near double digits.
On the international front, he said that despite disagreements with U.S. President Donald Trump over Iran and climate change, he would continue to work with the billionaire.
"I constantly talk to the American president, because it's my duty," he said. "It's the right way to do it because he is the head of the top power so it's necessary to anchor him to this partnership and multilateralism."
On Iran, he said he would go to Tehran in "due time", but added: "We must be more stringent with Iran on its ballistic activity, the missiles it shoots and which are not nuclear and Iran's action in the region."
